We often hear about the &#8220;nature versus nurture&#8221; debate, framing it as a battle between our genes and our environment. But in many cases it&#8217;s not a battle at all, it&#8217;s a partnership. The way our genes impact our health and traits may change depending on our environment.

Understanding both &#8220;nature&#8221; and &#8220;nurture&#8221; is especially important when we consider complex skills critical to success in life, like reading. Thanks to the contribution of over a million 23andMe® research participants, a <a href="https://pubmed.ncbi.nlm.nih.gov/40991152/" target="_blank" rel="noreferrer noopener">new study</a>, led by scientists from the University of Edinburgh, is helping to untangle how both genes and environment work to shape literacy.



<h2 class="wp-block-heading" id="h-the-reading-puzzle-nbsp">The Reading Puzzle&nbsp;</h2>



Literacy is a powerful predictor of life outcomes, from education level to income. For decades, researchers have tried to understand the roles genetics and environment play in why some people learn to read and spell more easily than others.



<figure class="wp-block-image alignleft size-full is-resized"><img loading="lazy" decoding="async" width="425" height="282" src="http://35.88.189.111/wp-content/uploads/2008/07/twins.jpg" alt="" class="wp-image-392" style="width:309px;height:auto" srcset="https://blog.pub.us-west-2.prd.23andme.us/wp-content/uploads/2008/07/twins.jpg 425w, https://blog.pub.us-west-2.prd.23andme.us/wp-content/uploads/2008/07/twins-300x199.jpg 300w" sizes="auto, (max-width: 425px) 100vw, 425px" /></figure>



Several <a href="https://pubmed.ncbi.nlm.nih.gov/23725549/" target="_blank" rel="noreferrer noopener">studies</a> of <a href="https://pubmed.ncbi.nlm.nih.gov/19076484/" target="_blank" rel="noreferrer noopener">twins</a> in the United States suggested an interaction between genes and environment. In these studies, how much influence genetics had on reading skills seemed to be higher in families with a higher socioeconomic status. In other words, genetics appeared to have a bigger impact on a child&#8217;s reading ability when they were in a more advantaged environment. This idea is called a gene-by-environment interaction.



However, the evidence of this gene-by-environment interaction was mixed in studies conducted in the <a href="https://pubmed.ncbi.nlm.nih.gov/19296213/" target="_blank" rel="noreferrer noopener">United Kingdom</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/28832969/" target="_blank" rel="noreferrer noopener">Australia</a>. This puzzle led researchers to ask: can we use modern genetic data to test this theory in large, diverse populations?



<h2 class="wp-block-heading" id="h-a-new-approach">A New Approach</h2>



Researchers utilized summary statistics from a 2022 <a href="https://blog.23andme.com/articles/study-identifies-genetic-links-to-dyslexia" target="_blank" rel="noreferrer noopener">genome-wide association study (GWAS) on dyslexia</a> to construct a polygenic score—a way of estimating someone’s genetic tendency toward a trait by adding up the small effects of thousands of DNA differences.



The team then applied this polygenic score to two large groups of children and adolescents in Australia and the United Kingdom to see if the score&#8217;s effect on reading and spelling skills was moderated by their family&#8217;s socioeconomic status. Socioeconomic status was used as a broad measure of environmental advantage, capturing factors like parental education level and household income.&nbsp;



<h2 class="wp-block-heading" id="h-what-was-discovered-two-parallel-paths">What Was Discovered: Two Parallel Paths</h2>



Both the dyslexia polygenic score (nature) and socioeconomic status (nurture) were significant predictors of reading and spelling performance. Together, demographic, genetic, and socioeconomic factors explained between 8% and 11.6% of the variation in reading skills.



However, the study found no interaction effect. Nature and nurture were both important, but they worked in parallel.



This means the influence of a person&#8217;s genetic predisposition was the same, regardless of their family&#8217;s socioeconomic background. In these groups, a higher genetic predisposition for reading provided a similar boost to children from all socioeconomic backgrounds.&nbsp;



<h2 class="wp-block-heading" id="h-the-bigger-picture">The Bigger Picture</h2>



This finding is an important reminder to scientists to consider different environments when looking for gene-by-environment interactions. While some earlier US-based studies suggested an interaction, the different environments in these large UK and Australian groups showed a different outcome. Suggesting that both our genes and our environment make their own distinct contributions to the development of this fundamental skill.



Of course, every study has its limitations. The 23andMe research participants who contributed to the original GWAS are a self-selecting group and may not be perfectly representative of the general population. Additionally, only about 5% of 23andMe research participants said they had dyslexia, which is on the lower end of the <a href="https://pubmed.ncbi.nlm.nih.gov/18652545/" target="_blank" rel="noreferrer noopener">commonly cited 5–10% range</a>.



Even so, this large-scale study provides a crucial piece of the puzzle, emphasizing how vital it is to test scientific findings in diverse environments to get the full story.

23andMe Research Institute Attending ASHG 2025

Cannabis is already one of the most widely used drugs globally, and its use will likely grow even more as it becomes more socially accepted and legally available. For many the recreational use of cannabis poses few problems, but for as many as a third of users, it becomes problematic developing into an addiction or what scientists call cannabis use disorder. Research suggests that genetics may explain why.



<h2 class="wp-block-heading" id="h-searching-the-genome-for-clues">Searching the Genome for Clues</h2>



In collaboration with 23andMe Research Institute, researchers at the University of California, San Diego <a href="https://www.nature.com/articles/s41380-025-03219-2" target="_blank" rel="noreferrer noopener">published a study</a> today that found genetic links to cannabis use as well as links to psychiatric, cognitive, and physical health. The researchers used data from more than 130,000 people who consented to participate in 23andMe research. Participants answered survey questions on whether they had ever used cannabis (“lifetime use”) and, for those who had, how often they used it during their heaviest 30-day period (“frequency of use”). The team then conducted genome-wide association studies searching for genetic variants linked to ever trying cannabis and how often people used the drug.



<h2 class="wp-block-heading" id="h-what-the-data-revealed">What the Data Revealed</h2>



Researchers found that having ever used cannabis was associated with two genetic regions: CADM2—a gene <a href="https://blog.23andme.com/articles/scientists-identify-genes-associated-with-cannabis-use" target="_blank" rel="noreferrer noopener">previously linked</a> to cannabis and other substance use, impulsivity, and risk-taking—and GRM3. While GRM3 has been tied to alcohol use, schizophrenia, and certain personality traits, this is the first time it’s been linked to cannabis use. How often someone used cannabis was associated with a different variant also near CADM2, strengthening this gene’s role in cannabis behaviors. Both having ever used cannabis and how frequently someone used cannabis were genetically linked to other substance use, pain, and psychiatric conditions like depression. Researchers also created polygenic scores—which tally the effects of many different genetic variants—to estimate both the likelihood of ever having used cannabis and the frequency of cannabis use. These polygenic scores were able to replicate associations between cannabis use and substance use and mood disorders in two other independent research datasets (All of Us and BioVU). The researchers also uncovered novel associations with anxiety, celiac disease, HIV, and viral hepatitis.



<h2 class="wp-block-heading" id="h-why-this-research-matters">Why This Research Matters</h2>



Most genetic research on cannabis has focused on two points in the spectrum: first use and cannabis use disorder. But the stages in between—like how often someone uses cannabis—are just as important. Studying these “pre-addiction” traits may help determine who is more likely to progress from a casual user to someone with cannabis use disorder. This study was one of the first genome wide association studies to look at traits that may lead to cannabis use disorder.&nbsp;



Traits like frequency of cannabis use can reveal genetic factors that shape vulnerability before addiction develops. Understanding these factors could eventually help predict risk for cannabis use disorder and related health conditions.



<h2 class="wp-block-heading" id="h-more-than-just-dna">More Than Just DNA</h2>



Like all research there are some important considerations to keep in mind for this study:



<ul class="wp-block-list">
<li>While this research focused on genetics, many non-genetic factors may also play a significant role in a person&#8217;s likelihood of using cannabis or developing cannabis use disorder.</li>



<li>The study was conducted in people of European descent (based on an analysis of their local genetic ancestry), so the findings may not fully apply to people of other ancestries.</li>



<li>The measure of frequency (use days in a 30-day window) of using cannabis doesn’t capture full patterns such as the duration of regular use or quantity consumed.</li>



<li>While GRM3 is a promising lead, more work is needed to understand how the genetic variant in this region affects cannabis use biology.</li>
</ul>



<h2 class="wp-block-heading" id="h-the-road-ahead">The Road Ahead</h2>



Future research will need to expand to larger and more diverse cohorts and include other cannabis-related traits such as craving, withdrawal, and response to cannabis. Combining genetic insights from multiple stages of cannabis use could:



<ul class="wp-block-list">
<li>Improve the discovery of new genetic variants</li>



<li>Help build predictive models for problematic use</li>



<li>Clarify how cannabis genetics intersect with physical and mental health</li>
</ul>



Takeaway: Studying genetic influences on early cannabis use behaviors could eventually help predict risk for cannabis use disorder and related health conditions, and may help shed light on who is most at risk for cannabis use disorder.&nbsp; These findings mark an important step toward understanding the genetics of cannabis use and its health consequences.

New Genetic Insights Into Cannabis Use

<h6 class="wp-block-heading" id="h-a-new-study-may-help-identify-and-more-quickly-help-the-60-of-people-with-major-depression-who-do-not-get-relief-from-their-initial-treatments">A new study may help identify and more quickly help the 60% of people with major depression who do not get relief from their initial treatments. </h6>



It is estimated that 60% of patients with major depressive disorder don&#8217;t find relief from their first medication, and as many as one-third develop <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC10503923/" target="_blank" rel="noreferrer noopener">treatment-resistant depression</a>, which is often defined as still experiencing symptoms after trying at least two antidepressants.



Researchers at Johnson &amp; Johnson and the 23andMe Research Institute used advanced machine learning techniques to accurately identify those at most risk for treatment-resistant depression, a massive breakthrough for those suffering with this condition.



The groundbreaking research, published this week in the journal <a href="https://pubmed.ncbi.nlm.nih.gov/41028019/" target="_blank" rel="noreferrer noopener">Scientific Reports</a>, used only self-reported information from about 23,000 people who consented to participate in 23andMe research. The model included a total of 101 predictive factors, including such things as age, symptoms that persist between episodes of depression, the duration of episodes of depression, stress levels, and suicidal thoughts. 



Using this predictive model, researchers were able to accurately predict those at the highest risk for treatment-resistant depression 78% of the time, according to the study.&nbsp;



The predictive model did not use either genetics or lab results, just questions that can be easily assessed by a clinician.



<h2 class="wp-block-heading">Why This Matters</h2>



<figure class="wp-block-image alignright size-full is-resized"><img loading="lazy" decoding="async" width="508" height="531" src="http://35.88.189.111/wp-content/uploads/2025/10/drug-bottle.png" alt="" class="wp-image-34304" style="width:161px;height:auto" srcset="https://blog.pub.us-west-2.prd.23andme.us/wp-content/uploads/2025/10/drug-bottle.png 508w, https://blog.pub.us-west-2.prd.23andme.us/wp-content/uploads/2025/10/drug-bottle-287x300.png 287w" sizes="auto, (max-width: 508px) 100vw, 508px" /></figure>



Typically, antidepressants used to treat major depression take a little time to work, up to a month or a month and a half. When a treatment does not work, clinicians often prescribe an alternative medication. When someone with depression fails to respond to at least two different medications, they are deemed to have treatment-resistant depression. In many cases, it can take around a year for someone to finally be diagnosed with treatment-resistant depression.



That long delay in finding effective treatment has a cost, not just in the time it takes to identify treatment but in the prolonged suffering for those in the throes of depression, unable to get relief.&nbsp;



The promise of the kind of predictive modeling described in this new study is that it would give both people with depression and clinicians who treat them a tool to flag those who might not respond to standard therapies.



Instead of waiting to see if initial treatments are effective, it may accelerate the process of finding alternatives. Additionally, this predictive model only utilizes patient-reported information; no expensive testing is required.&nbsp;



<h2 class="wp-block-heading">More About the Predictive Model</h2>



The model identified eight primary factors that predict treatment resistance, as reported by research participants. Each offers different dimensions of their depression.



<figure class="wp-block-image alignleft size-full is-resized"><img loading="lazy" decoding="async" width="275" height="252" src="http://35.88.189.111/wp-content/uploads/2025/10/depression.png" alt="" class="wp-image-34307" style="width:184px;height:auto"/></figure>



Participants reported on the different symptoms that persisted between the episodes of depression. They reported on how long each episode of depression lasted, and how many years they&#8217;d experienced these periodic episodes. Also included in the self-reported data were levels of stress, or whether they had recurring post-traumatic stress, and two critical factors that looked at more external stressors and life events. Also factored into the modeling was a participant&#8217;s age and whether they had suicidal thoughts. Finally, the model included the self-reported timing between episodes of depression, which was significant when the time between episodes was shorter.



Using these factors and advanced machine learning the researchers were able to accurately distinguish between those who were treatment-resistant and those who responded to treatment. An accurate way to identify if someone will or will not respond to treatment could translate into meaningful clinical benefits. It could mean the difference between waiting months for effective treatment instead of years.&nbsp;



<h2 class="wp-block-heading">More Personalized Depression Care</h2>



This research represents a crucial step toward more personalized mental health treatment and a move away from a &#8220;one-size-fits-all&#8221; approach to treatment of depression.&nbsp;



For the millions of people living with depression, this work represents a path toward precision care, shortening the time to effective treatment and improving quality of life.



The future of depression treatment lies not just in developing new medications, but in better understanding who needs what treatment when. This predictive model brings us measurably closer to that goal, promising a world where effective depression treatment is not a matter of luck, but of precision.

At the 2025 World Conference on Lung Cancer in Barcelona, the 23andMe Research Institute, in collaboration with Troper Wojcicki Philanthropies and the health data software company Lifebit, introduced an open-source platform that could help fast-track research discoveries through a powerful new cancer data repository.



The announcement comes just a year after the start of the<a href="https://www.23andme.com/lung-cancer" target="_blank" rel="noreferrer noopener"> Lung Cancer Genetics Study</a>, spearheaded by 23andMe and bringing together more than 20 lung cancer advocacy and science organizations to recruit 10,000 people diagnosed with lung cancer. Their goal is to develop new ways to identify those at highest risk for lung cancer early, while also finding possible new treatments for this deadly cancer.



<h2 class="wp-block-heading">The Personal Drive Behind the Mission</h2>



The effort is personal for many of the advocates who are part of the collaboration and also for Anne Wojcicki, founder and CEO of the 23andMe Research Institute. Anne&#8217;s sister Susan Wojcicki died of lung cancer last year, just as the study began.



&#8220;My sister was passionate about understanding the science behind lung cancer so future generations could prevent the disease and treat it. The Lung Cancer Genetics Study is a step towards achieving that.” Anne said.



In the months before her death, <a href="https://blog.23andme.com/articles/a-legacy-of-hope-in-the-fight-against-lung-cancer" target="_blank" rel="noreferrer noopener">Susan had been very involved in helping to create the study with the hope that it could help others</a>. The idea was not just to leverage genetic data for insights into lung cancer but also to create a repository of data that would be available to as many qualified researchers as possible.&nbsp;



The platform — created through the collaboration between the 23andMe Research Institute, Troper Wojcicki Philanthropies, and Lifebit — offers a secure, open-source data platform for researchers to access this novel dataset. Powered by Lifebit&#8217;s Health Data Ecosystem, the platform provides qualified researchers with no-cost access to de-identified data from people diagnosed with lung cancer who have consented to participate in this research.&nbsp;



&#8220;More people die of lung cancer each year than breast, colon, and prostate cancer combined, yet it is one of the least funded for research. It’s important for this powerful new tool to be available at no cost to qualified researchers so that the best minds can work on unlocking the genetic insights that may lead to a cure,&#8221; said Anne.



<h2 class="wp-block-heading">Building a One-of-a-Kind Data Resource</h2>



Since launching the <a href="https://blog.23andme.com/articles/23andme-launches-new-genetic-study-of-lung-cancer" target="_blank" rel="noreferrer noopener">Lung Cancer Genetics Study</a>, more than 1,200 people diagnosed with lung cancer have enrolled to participate in the research. The goal is to enroll 10,000 people by 2027, but the study has already assembled one of the most diverse cohorts ever for lung cancer genetic research.&nbsp;

Genetics is just one of many factors involved in why some people develop lung cancer. Exposure to tobacco smoke is perhaps the best-known risk factor; however, <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC2409903/" target="_blank" rel="noreferrer noopener">80 to 90%</a> of people with a history of tobacco exposure never get lung cancer, and many people without tobacco exposure get the disease. These facts underscore the importance of investigating other, less well-known risk factors, like air pollution, radon exposure, and workplace-related exposures.



And there&#8217;s much more we don&#8217;t know about lung cancer. Many do not realize, for instance, that lung cancer is the <a href="https://www.cancer.org/content/dam/cancer-org/research/cancer-facts-and-statistics/annual-cancer-facts-and-figures/2025/2025-cancer-facts-and-figures-acs.pdf" target="_blank" rel="noreferrer noopener">number one cause of cancer death in women</a> and <a href="https://www.massgeneralbrigham.org/en/about/newsroom/articles/most-common-cancers-in-women#:~:text=It%20may%20not%20surprise%20you,in%20women%20and%20people%20AFAB." target="_blank" rel="noreferrer noopener">the second most common cancer in women</a>. Although lung cancer overall is decreasing because of declines in tobacco use, lung cancer among people who have never smoked <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7431055/#:~:text=As%20expected%2C%20the%20primary%20factor%20leading%20to,non%2Dsmokers%20has%20been%20noted%20to%20be%20increasing." target="_blank" rel="noreferrer noopener">is stable or increasing</a>, and <a href="https://www.webmd.com/lung-cancer/features/lung-cancer-women-who-never-smoked" target="_blank" rel="noreferrer noopener">two-thirds of people diagnosed with lung cancer with no smoking history are women</a>.&nbsp;



Understanding the genetics of lung cancer may help unravel some of the factors underlying those statistics. Additionally, learning more about the underlying genetics could provide researchers with more insight into the biological mechanisms of the disease, aiding in the development of improved therapies and new diagnostics.&nbsp;



The de-identified data that participants in the Lung Cancer Genetic Study consented to share isn’t limited to just genetics. Many participants also chose to provide self-reported clinical, lifestyle, and even tumor biomarker data. The study will also follow participants over time, gathering important longitudinal data to help researchers understand the progression of cancer as well as the response to treatments.&nbsp;



<h2 class="wp-block-heading">Empowering Researchers</h2>



By opening up access to qualified researchers, the collaborators aim to address significant gaps in current lung cancer research, break down institutional silos, and remove barriers to dataset access, thereby accelerating research progress.&nbsp;



&#8220;We&#8217;re delivering more than a data system — we&#8217;re enabling an entirely new model for research equity and access,&#8221; said Nadia Litterman, PhD, Director of Scientific Affairs and Partnerships at Troper Wojcicki Philanthropies.

Inside Health Huddle LIVE: Athletes, Experts & Doctors on Longevity, Genetics & Wellness

September is Sickle Cell Awareness Month, which offers us another chance to highlight some of the work 23andMe and its collaborators have done over the years.



Earlier this month, researchers from 23andMe,<a target="_blank" href="https://www.nih.gov/" rel="noreferrer noopener"> the the National Institutes of Health</a>, and <a target="_blank" href="https://www.hopkinsmedicine.org/som/" rel="noreferrer noopener">Johns Hopkins University School of Medicine</a> published new data on the association between sickle cell trait and blood clots. The new findings highlight the importance of this ongoing research and our overall efforts to illuminate this condition.



At 23andMe, knowledge is power, and understanding risks offers people opportunities to mitigate them.&nbsp;



<h2 class="wp-block-heading" id="h-awareness-and-research">Awareness and Research</h2>



But more than that, 23andMe also offers a unique research model that allows individuals to learn about their genetic likelihood of developing a condition and participate in innovative genetic research that could potentially find new treatments.



As part of our <a href="http://www.23andme.com/sickle-cell" target="_blank" rel="noreferrer noopener">Sickle Cell Carrier Status Awareness Program</a>, 23andMe has collaborated with academics and advocacy organizations to increase <a href="https://blog.23andme.com/articles/sickle-cell-awareness-2">understanding of sickle cell</a>. In addition, we’re providing resources for those with sickle cell trait and sickle cell disease. With the help of the<a href="https://www.sicklecellga.org/" target="_blank" rel="noreferrer noopener"> Sickle Cell Foundation of Georgia, Inc. (SCFG)</a>,<a href="https://www.btsscycle.org/" target="_blank" rel="noreferrer noopener"> Breaking the SSickle Cell Cycle</a>,<a href="https://www.sc101.org/" target="_blank" rel="noreferrer noopener"> Sickle Cell 101</a>, and the<a href="https://www.msm.edu/" target="_blank" rel="noreferrer noopener"> Morehouse School of Medicine</a>, we’re working with Black communities to promote awareness. 



We are not alone in this effort. Recently, the NBA, the WNBA, and Wilson Sporting Goods began the #IBall4SickleCell social media campaign to raise awareness. The groups participating in the effort are Breaking the SSickle Cell Cycle, the American Red Cross of Tennessee, and New York Presbyterian’s Dalio Center for Health Justice. Learn more about sickle cell, the campaign, and how to help<a href="https://www.sicklecellball.com/" target="_blank" rel="noreferrer noopener"> here</a>. 



From all this work and research, we have learned much about sickle cell and the people it impacts most. However, much work is still needed to improve people’s understanding of sickle cell.



<h2 class="wp-block-heading" id="h-more-on-sickle-cell-anemia-sickle-cell-trait">More on Sickle Cell Anemia, Sickle Cell Trait</h2>



Although many people have heard of sickle cell, often they do not know the difference between sickle cell trait and sickle cell anemia.



To have sickle cell anemia, one must inherit two copies of the HbS variant in the HBB gene—one copy from each biological parent. Typical signs and symptoms include anemia, pain episodes, and frequent infection.



People with just one copy of the HbS variant are called carriers. They’re also said to have <a target="_blank" href="https://www.cdc.gov/ncbddd/sicklecell/traits.html" rel="noreferrer noopener">sickle cell trait</a>. People with sickle cell trait are not expected to have sickle cell anemia. They typically do not experience any health complications. However, in rare cases, people with the sickle cell trait may experience some health impacts. Current research, including our study, is underway to understand better and spread awareness about the complications someone with SCT may experience.



Importantly, carriers can pass their variant on to their future children. If their partner has the HbS variant or another variant in the HBB gene, there’s a 25 percent chance that each child may have sickle cell anemia or a related blood disorder.&nbsp;&nbsp;



<h2 class="wp-block-heading" id="h-23andme-s-sickle-cell-anemia-carrier-status-report">23andMe’s Sickle Cell Anemia Carrier Status Report**</h2>



23andMe’s<a target="_blank" href="https://www.23andme.com/topics/carrier/sickle-cell-anemia/" rel="noreferrer noopener"> Sickle Cell Anemia Carrier Status Report</a>, which meets FDA requirements for clinical and analytical validity, looks at the HbS variant in the HBB gene linked to sickle cell anemia.



Sickle cell anemia is the most severe form of sickle cell disease. Three hundred million people worldwide and one in 13 Black and African Americans in the United States have sickle cell trait, making them carriers for sickle cell anemia.



In addition to informing people if they have one copy of the HbS variant and are carriers for sickle cell anemia, <a href="https://blog.23andme.com/articles/23andme-updates-carrier-status-report-on-sickle-cell-anemia">23andMe’s report </a>can also tell individuals if they have two copies of the tested variant and if they are at risk of developing symptoms. However, the report does not describe one’s overall risk of developing symptoms. 



Because the HbS variant is more common in certain populations, the Sickle Cell Anemia report is most relevant to people of African, Middle Eastern, and South Asian descent, as well as people from the Caribbean, the Mediterranean, and parts of Central and South America.

**The 23andMe PGS test uses qualitative genotyping to detect select clinically relevant variants in the genomic DNA of adults to report carrier status and reporting and interpreting genetic health risks. The relevance of each report may vary based on ethnicity. Our carrier status reports can be used to determine carrier status but cannot determine if you have two copies of any genetic variant. These carrier reports are not intended to tell you anything about your risk for developing a disease in the future, the health of your fetus, or your newborn child’s risk of developing a particular disease later in life.

Editor&#8217;s note 7/8/2024: This post has been updated since 2020. In addition, We do not support uploading DNA data obtained from other testing services to 23andMe. This article explains the risks of uploading your DNA data to third party services.
With all of <a class="waffle-rich-text-link" href="https://www.23andme.com/compare-dna-tests/">23andMe&#8217;s services</a>, you’re in charge of your genetic data. That means we let you decide what information you want to learn and what information you want to share. However, you need to be informed about the risks of sharing your genetic data with other services. This includes understanding the implications if you decide to upload DNA to 23andMe or any third-party service.
After receiving <a class="waffle-rich-text-link" href="https://www.23andme.com/dna-reports-list/">personalized genetic reports</a> from 23andMe, customers can choose to download their raw DNA data. Some customers may do this to upload their data to third-party services, which offer to interpret their raw DNA data to find new genetic relatives or get additional genetic reports. However, 23andMe cannot vouch for the scientific validity or accuracy, or clarity in communication of results of any such third-party services. In fact, only 23andMe offers a consumer genetic test with health reports that have FDA&#8217;s independent assurance of validity and clear results (without requiring a prescription).
Beyond concerns about scientific validity, uploading your raw DNA data to a third-party service can also put <a href="https://www.23andme.com/privacy/">your data privacy</a> at risk. In part, this is why 23andMe provides important warnings to its customers before they choose to download.
<h2>What are some of the risks of uploading your DNA data to a third-party website? </h2>
<div id="attachment_27862" style="width: 310px" class="wp-caption alignright"><a href="https://blog.23andme.com/articles/how-to-be-careful-with-your-raw-dna-data/what-is-dna-upload" rel="attachment wp-att-27862"><img loading="lazy" decoding="async" aria-describedby="caption-attachment-27862" class="size-medium wp-image-27862" src="http://35.88.189.111/wp-content/uploads/2020/01/What-is-DNA-Upload-300x128.jpg" alt="An illustration of the steps for downloading data." width="300" height="128" srcset="https://blog.pub.us-west-2.prd.23andme.us/wp-content/uploads/2020/01/What-is-DNA-Upload-300x128.jpg 300w, https://blog.pub.us-west-2.prd.23andme.us/wp-content/uploads/2020/01/What-is-DNA-Upload.jpg 512w" sizes="auto, (max-width: 300px) 100vw, 300px" /></a>Most consumer genetics companies, including 23andMe, allow you to download your own raw DNA data. At that point, the customer is free to do what they like with their raw DNA data, such as deciding to upload that raw DNA data to third-party services.</div>
At 23andMe, we’re clear with our users about the risks of using third-party services that provide additional health, wellness or trait insights. This is because only select genotype data used specifically in our Health reports have been individually validated for accuracy. While the rest of your data has undergone a general quality review, it has not been validated to the extent of the data underlying our official 23andMe reports. As a result, raw DNA data should not be used for medical purposes and we do not recommend the use of third-party services that claim to interpret raw DNA data to provide health information.
Consumers also cite concerns about law enforcement uploading crime-scene DNA data to third-party services to crack a cold case. Simply put, uploading crime-scene DNA data into the 23andMe environment is not possible because we do not support the upload of DNA data that has been processed by a third-party laboratory.
Further, 23andMe’s <a href="https://www.23andme.com/transparency-report/">Transparency Report</a> details our policy against releasing customer’s individual DNA data to any third party &#8211; including law enforcement &#8211; without receiving the customer’s explicit consent, unless required by law.
However, this concern about law enforcement upload of crime scene DNA data is a real one that we warn customers about should they choose to upload their DNA data to other third party platforms, including public genealogy services or other third party services that facilitate DNA data upload.
But there’s another form of vulnerability that’s less well-understood: Within databases that allow for raw DNA data uploads with access to relative matching features, people with malicious intent can upload real or fake “<a href="https://en.wikipedia.org/wiki/Trojan_horse_(computing)">Trojan Horse</a>” genetic profiles for access to your personal identifying information. They could even infer your specific DNA variants—such as information about any disease risk variants you might carry. This is one reason why we don&#8217;t support uploading DNA to 23andMe.
<h2>How can that happen?</h2>
<ul>
<li>Many relative-matching services allow you to see the exact section or sections of DNA you share with each relative.*</li>
<li>If uploading DNA data is allowed, it means you no longer know for sure that your relative’s profile is actually controlled by your relative, and a malicious actor could upload real or fake DNA data to deduce information about you based on sections of matching DNA, including any disease risk variants you might have.</li>
<li>Even if shared segments aren’t shown, there are still ways that people with malicious intent can deduce some of your DNA variants.</li>
</ul>
<img loading="lazy" decoding="async" class="size-medium wp-image-27863 alignright" src="https://blog-api.23andme.com/wp-content/uploads/2020/01/How-Uploading-Creates-Risk-300x202.jpg" alt="" width="300" height="202" srcset="https://blog.pub.us-west-2.prd.23andme.us/wp-content/uploads/2020/01/How-Uploading-Creates-Risk-300x202.jpg 300w, https://blog.pub.us-west-2.prd.23andme.us/wp-content/uploads/2020/01/How-Uploading-Creates-Risk.jpg 512w" sizes="auto, (max-width: 300px) 100vw, 300px" />
This vulnerability was recently described in two reports: one at the University of Washington and another at the University of California, Davis. The authors of these reports explain several ways an “adversary” can deduce people&#8217;s genotypes “either at key positions or at many sites genome-wide” in databases that allow DNA data uploads with relative matching. This highlights the risks associated with uploading DNA to 23andMe or similar services.
Both reports outline specific ways for services to mitigate risk, such as limiting the information displayed in relative-matching features.
While these practices may reduce risk, we believe the simplest and most effective defense is to not allow individuals genotyped through other testing services to upload their DNA data to 23andMe for the purpose of discovering genetic relatives.
In the past, 23andMe has allowed DNA uploads from other consumer genetic testing services in very specific circumstances. Specifically, on DNA Day in April 2018, 23andMe allowed individuals who tested at other companies to upload their results to access a subset of our trait reports, but 23andMe has not enabled the discovery of new relatives for these accounts.
<h2>How does 23andMe ensure that only real, consenting individuals participate in our service? </h2>
In a word, spit.
When you spit into the tube, you’re embarking on the adventure of a lifetime. You’re also trusting 23andMe with some of your most personal information.
Requiring a saliva sample is how 23andMe is able to verify that you’re a real person who chose to participate in the service. While it might be easy to upload fake DNA data, it’s another matter entirely to fake a spit sample, which requires filling a tube with more than two milliliters of spit. It’s how you know that “Linda-your-4th-cousin-who-you-didn’t-know-existed” is a real person who chose to do 23andMe. Linda had to spit in a tube, too.
<h2>What are some key questions you should ask?</h2>
When considering whether or not to upload your raw DNA data to another website, we encourage you to familiarize yourself with their privacy and security policies before you upload your raw DNA data.
Make sure to consider the following questions:
<ol>
<li>Before you upload your DNA data, ask yourself: do I really need to do this? Am I willing to risk the security and privacy of my DNA data by uploading it to a third-party service?</li>
<li>Do your research! Does the third-party service have a track record of strong privacy and data security?</li>
<li>How will the third-party service use your information?  How can your information be further shared with other third parties?</li>
<li>If you are not interested in discovering new relatives but you want additional DNA insights, does the other service explicitly exclude features relating to discovering genetic relatives?</li>
</ol>

Can You Upload DNA Data to 23andMe? 

Today is DNA Day, and while every day at 23andMe is about DNA, this one is extra special because it allows everyone to delight in the power of DNA.



Whether you are a 23andMe customer or just DNA curious, there is a lot you can do if you’d like to start or deepen your genetic journey and take action to participate in the new genomic age.



We’ll get to that, but first, take a moment to learn —or refresh your knowledge — about what we’re celebrating.



<h2 class="wp-block-heading" id="h-a-double-helix-celebration">A Double Helix Celebration</h2>



<a href="https://www.genome.gov/dna-day">DNA Day</a> commemorates the anniversary of the 1953 discovery of the double helix structure of DNA and the 2003 completion of the human genome project that led to the sequencing of the human genome for the first time. That code represents the building blocks of life, and it gives us access to information that has already led to medical and scientific breakthroughs, as well as an understanding of the human story.



23andMe was founded in 2006, not long after the publication of the mapping of the human genome. Our mission then and now is to help people access, understand, and benefit from the human genome.&nbsp;



Not too long ago, 23andMe surpassed 15 million genotyped customers, each of whom chose to begin their genetic journey with us. We’d like to invite you along as well, or if you’re already a customer, we’d like to share with you how to go a little further on this journey.



<h2 class="wp-block-heading" id="h-first-steps">First Steps</h2>



If you’re not yet a customer, your first step could be to spit in a tube provided in one of our test kits and send it to our lab. At the lab, technicians extract DNA from your saliva, which is placed on a genotyping chip.



Here’s <a href="https://www.youtube.com/watch?v=BtxX_3nVDao">a little video</a> about the different services we offer customers and what they can tell you about your health, traits, and ancestry.



Of course, if you don’t want to use 23andMe or don’t want to use a genetic test, there are plenty of great and free options for learning more about genetics. One of our go-to resources is the <a href="https://www.genome.gov/about-genomics">National Human Genome Research Institute</a>, but many other options exist.



<h2 class="wp-block-heading" id="h-open-and-explore-your-reports">Open and Explore Your Reports</h2>



Like with any exploration, you don’t know what you might find in using 23andMe that could draw you deeper into your DNA exploration.



Customers might want to learn more about their health, find DNA relatives, or learn about their genetic ancestry. Some people are just curious and want to geek out on genetics.&nbsp;



If you’ve taken that first step and tested, the next step is to open your reports. Some Genetic Health Risk Reports*—such as those on Late-Onset Alzheimer’s Disease, BRCA1/BRCA2 (Selected Variants), and Parkinson’s Disease, for instance—require an additional opt-in before opening. But whatever reports you’re looking at, we have tutorials on navigating them and where to start.



Our <a href="https://www.23andme.com/dna-ancestry/">Ancestry Service</a> has the most comprehensive ancestry breakdown on the market; it now includes more than 3000 geographic regions, an automatic family tree builder, and more than 30 trait reports. As 23andMe grows, so does our ability to improve the granularity and specificity of the regions we offer in our ancestry report. For instance, we added 36 new Genetic Groups in France and Belgium.&nbsp;



23andMe’s <a href="https://www.23andme.com/dna-health-ancestry/">Health + Ancestry Service</a> includes everything you get in the Ancestry Service plus health predisposition reports (including FDA-authorized reports), wellness reports, carrier status reports, and a family health history tree feature. In all, the service includes more than 150 personalized reports.



The 23andMe+ Premium membership includes everything in the Health + Ancestry Service plus more than 30 PRS reports, including reports on three of the most common forms of cancer and reports on heart health and mental health conditions like anxiety and depression. In addition, the service includes FDA-authorized reports on how your genetics may impact the way you process certain types of medications.** 23andMe+ Premium also includes tools and features such as <a href="https://blog.23andme.com/articles/stay-on-track-with-23andme-health-tracks">Health Tracks</a>SM and <a href="https://blog.23andme.com/articles/a-health-action-plan-for-you">Health Action Plan</a> to help you get even more personalized recommendations. Most recently, we’ve added a new ancestry feature called <a href="https://blog.23andme.com/articles/23andmes-historic-matches">Historical Matches</a>SM that helps determine whether you connect to one or more of 335 historical people across the globe.&nbsp;



For those who want our most advanced and comprehensive health membership, we offer <a href="https://www.23andme.com/total-health/">23andMe+ Total Health</a>***, which includes next-generation sequencing that detects 200x more disease-causing genetic variants*.

<h2 class="wp-block-heading" id="h-participate-in-research">Participate in Research</h2>



What is something in you, something in your DNA, that could help scientists better understand a disease or develop a new treatment or cure?&nbsp;



One of the many innovations 23andMe pioneered is our research model, which allows people to consent to participate in research. The guiding principle for 23andMe is transparency and choice. It’s a choice whether someone wants to access their genetic information, and 23andMe also gives our customers a choice about whether they want to participate in research. More than 80 percent of 23andMe customers actively consent to participate in research.&nbsp;



Our research database, which contains aggregated de-identified genetic and phenotypic data, is by far the largest research database of its kind.&nbsp;



It’s helped not just our scientists but academic and institutional researchers with whom we’ve collaborated on more than <a href="https://research.23andme.com/publications/#publications">250 publications</a> on neurological conditions, cancers, and rare diseases. There are also ongoing research studies for <a href="https://www.23andme.com/PD/">Parkinson’s Disease,</a> <a href="https://www.23andme.com/genetic-insights-into-colorectal-cancer-black-community/">Colorectal Cancer within the Black Community</a>, and <a href="https://www.23andme.com/sickle-cell/">Sickle Cell</a>. And we continue to work on other conditions, including <a href="https://www.23andme.com/depression-bipolar/">depression and bipolar disorder</a>, <a href="https://www.23andme.com/sarcoidosis-representation/">sarcoidosis</a>, and <a href="https://you.23andme.com/covid19-study/">COVID</a>.&nbsp;



Another aspect of this work is ensuring that our research is more representative and thus benefits people of all backgrounds. Unfortunately, much of genetic research to date lacks diversity, which has meant that people of non-European backgrounds often do not benefit from those insights. 23andMe is trying to change that. Our Black Representation in Genomic Research study, for instance, has made great strides at engaging with communities that have historically been left out of research.&nbsp;



You can also help. If you’re a customer of 23andMe, you can consent to participate in research at any time through your Account Settings; if you’re not, you can seek out opportunities to participate in research through the <a href="https://allofus.nih.gov/">National Institutes of Health’s All of Us</a> effort, for example, or the Veteran’s Administration <a href="https://www.research.va.gov/mvp/">Million Veterans Program</a>.



<h2 class="wp-block-heading" id="h-share-your-story">Share Your Story</h2>



It’s always been heartening for us at 23andMe to hear from our customers and those who participate in our research about how launching their DNA journey has impacted them.&nbsp;



Whether they’ve learned more about their <a href="https://blog.23andme.com/articles/23andme-connects-living-family-to-enslaved-african-american-from-historic-site">family’s ancestral journey</a>, discovered <a href="https://www.youtube.com/watch?v=hbWirWghCJA">life-saving information</a> about family members, or joined with others to <a href="https://www.youtube.com/watch?v=2JzErEQFPIU">participate in crucial genetic research</a>, their stories inspire us all.&nbsp;



If you have a story to share, <a href="https://www.23andme.com/stories/#submit">we’d love to hear it</a>.

*23andMe health predisposition reports include both reports that meet FDA requirements for genetic health risks and reports that are based on 23andMe research and have not been reviewed by the FDA. The test uses qualitative genotyping to detect select clinically relevant variants in the genomic DNA of adults from saliva for the purpose of reporting and interpreting genetic health risks. It is not intended to diagnose any disease. Your ethnicity may affect the relevance of each report and how your genetic health risk results are interpreted. Each genetic health risk report describes if a person has variants associated with a higher risk of developing a disease, but does not describe a person’s overall risk of developing the disease. The test is not intended to tell you anything about your current state of health or to be used to make medical decisions, including whether or not you should take a medication, how much of a medication you should take, or determine any treatment. For certain conditions, we provide a single report that includes information on both carrier status and genetic health risk. 



Warnings &amp; Limitations: The 23andMe PGS Genetic Health Risk Report for BRCA1/BRCA2 (Selected Variants) is indicated for reporting 44 variants in the BRCA1 and BRCA2 genes. The report describes if a person&#8217;s genetic result is associated with an increased risk of developing breast cancer and ovarian cancer and may be associated with an increased risk for prostate cancer, pancreatic cancer, and potentially other cancers. The variants included in this report do not represent the majority of the BRCA1/BRCA2 variants in people of most ethnicities. This report does not include variants in other genes linked to hereditary cancers and the absence of variants included in this report does not rule out the presence of other genetic variants that may impact cancer risk. This report is for over-the-counter use by adults over the age of 18 and provides genetic information to inform discussions with a healthcare professional. The PGS test is not a substitute for visits to a healthcare professional for recommended screenings or appropriate follow-up. Results should be confirmed by an independent genetic test prescribed by your own healthcare provider before taking any medical action. For important information and limitations regarding each genetic health risk report, visit <a href="https://www.23andme.com/test-info/">23andme.com/test-info/</a>. 



**23andMe PGS Pharmacogenetics reports: The 23andMe test uses qualitative genotyping to detect 3 variants in the CYP2C19 gene, 2 variants in the DPYD gene, and 1 variant in the SLCO1B1 gene in the genomic DNA of adults from saliva for the purpose of reporting and interpreting information about the processing of certain therapeutics to inform discussions with a healthcare professional. It does not describe if a person will or will not respond to a particular therapeutic. Our CYP2C19 Pharmacogenetics report provides certain information about variants associated with the metabolism of some therapeutics and provides interpretive drug information regarding the potential effect of citalopram and clopidogrel therapy. Our SLCO1B1 Pharmacogenetics report provides certain information about variants associated with the processing of some therapeutics and provides interpretive drug information regarding the potential effect of simvastatin therapy. Our DPYD Pharmacogenetics report does not describe the association between detected variants and any specific therapeutic. Results for DPYD and certain CYP2C19 results should be confirmed by an independent genetic test prescribed by your own healthcare provider before taking any medical action. Warning: Test information should not be used to start, stop, or change any course of treatment and does not test for all possible variants that may affect metabolism or protein function. The PGS test is not a substitute for visits to a healthcare professional. Making changes to your current regimen can lead to harmful side effects or reduced intended benefits of your medication, therefore consult with your healthcare professional before taking any medical action.

Happy DNA Day 2024

Cancer casts its shadow on almost all of us. Whether we&#8217;re facing our own diagnosis or that of a spouse, a parent, a child, a friend, or another loved one, we can muster the courage we need in those moments by knowing we are not alone.



<h2 class="wp-block-heading" id="h-beat-cancer">Beat Cancer</h2>



We at 23andMe are encouraged by the White House’s recent designation of April as National Cancer Prevention and Early Detection Month to rally support for those affected and their families and highlight the importance of prevention and screening.



But beyond simply naming the month, this is part of a collective effort to raise awareness that includes <a href="https://www.preventcancer.org/wp-content/uploads/2024/03/2024_White_House_partner_letter_Cancer_Prevention_Early_Detection_FINAL.pdf">support from 84 non-profit and patient advocacy organizations</a>. Each group focuses on expanding cancer screening, research, and treatments.

<h2 class="wp-block-heading" id="h-progress">Progress</h2>



So much progress has been made already — <a href="https://www.cdc.gov/hpv/parents/vaccine/six-reasons.html">vaccines against human papillomavirus</a> promise to slash the rates of cervical cancer; cancer screening has <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10405449/">saved millions of lives</a> in the last three decades; new <a href="https://www.cancer.gov/news-events/press-releases/2020/lung-cancer-treatments-mortality-drop">treatments for lung cancer</a> have reduced mortality rates; and immunotherapies such as <a href="https://www.cancer.gov/about-cancer/treatment/research/car-t-cells">CAR-T cell therapy</a> have improved outcomes for many types of cancer.



However, much more needs to be done. Every year, more than 1.8 million people in the United States are <a href="https://www.cancer.gov/about-cancer/understanding/statistics">diagnosed with cancer</a>, and more than 600,000 people die each year, making it the <a href="https://www.cdc.gov/nchs/fastats/leading-causes-of-death.htm">second leading cause of death</a> behind heart disease.&nbsp;



Every cancer is different, but early detection and treatment offer the best outcomes for all cancers. Improved awareness about cancer screening — regular mammograms and colorectal cancer screening, for instance — can go a long way toward early detection.&nbsp;



Knowing one&#8217;s risk by learning about one&#8217;s family cancer history, or through genetic testing, or simply through identifying risk factors in one&#8217;s life can help identify those at higher risk and direct them toward preventive care or enhanced screening.



<h2 class="wp-block-heading" id="h-the-power-of-knowing">The Power of Knowing</h2>



23andMe wants to show our support for this new effort but also share a little about how we are raising awareness about cancer, alerting people of their potential risk for different forms of cancer, and adding to the growing body of research into cancer to potentially identify causes and cures.



In the coming weeks, we’ll share more about what 23andMe has done and is doing to help people better understand their genetic risk and family cancer history and how that knowledge is a formidable tool for cancer prevention.

Improving Cancer Outcomes Through Early Diagnosis and Treatment

Fundamental, common humanity unites every person on the planet: DNA. Some use race and biology to explain what are, in reality, social and cultural differences between people. It’s a fact that we humans are genetically 99.5 percent identical.&nbsp;



23andMe is a brand that leads with science. We fundamentally believe that we are more alike than we are different. Understanding that ridding ourselves of socially constructed ‘isms’ — like racism or classism —frees everyone. When we step out of systems of “us” vs “them” and bear witness to the oppression of people everywhere, humanity takes center stage.&nbsp;



Isabel Wilkerson’s biographical New York Times best-selling book, Caste, inspired Ava DuVernay’s new film ORIGIN. As with the book, DuVernay’s moving film adaptation — starring Aunjanue Ellis-Taylor as Wilkerson — analyzes discrimination and the connections between American racism, Nazi persecution of Jews, and India&#8217;s caste system.&nbsp;



It is the 0.5 percent that makes us each genetically different from one another and has also bred hatred across the world.



23andMe believes that focusing on all that we share as humans, and celebrating what makes us unique, could bring the world together. So for the next 23 days of January, 23andMe will donate 100 seats daily, to the <a href="https://www.seat16.com/">Seat16 program</a> which has a goal of getting 10,000 young people around the country to see the new film, ORIGIN.



Everyone deserves a place in this world and we believe in focusing on the things we share in common. Above all else, we want the world to remember that we are all 100 percent human.



ORIGIN will be in select theaters starting on January 19, 2024. 23andMe CEO and Co-founder Anne Wojcicki helped produce the film. You can see the ORIGIN film trailer <a href="https://www.youtube.com/watch?v=pAweg5PaMuw">here.</a>

Crucible Moments in 23andMe’s History

Since 2019, 23andMe customers have had the option to utilize authenticator app 2-factor authentication, which adds an extra layer of security to their account. Starting today, we are requiring all customers use a second step of verification to sign into their account.&nbsp;



<h6 class="wp-block-heading" id="h-what-is-2-step-verification">What is 2-Step Verification?</h6>



2-step verification (2SV), also referred to as 2-factor authentication, requires customers to provide two distinct steps to sign in before accessing their accounts. In combination with a username and password, customers will be asked for a verification code. 



Depending on what method customers choose to use, that code will either be generated by an authenticator app, or sent to their email if they use email 2-step verification. This code is another way to verify the customer’s identity before accessing their account.



<h6 class="wp-block-heading" id="h-setting-up-2-step-verification">Setting Up 2-Step Verification</h6>



New customers will be automatically enrolled in email 2SV when they create their account. Existing customers who do not already use an authenticator app will also be automatically enrolled in email 2SV, and will receive an email containing their verification code at their next sign-in. 



Existing customers who already use an authenticator app, can continue to use that option. New customers who want to use an authenticator app, such as Google Authenticator™ mobile app, instead of email 2SV, can set up the authenticator app using the instructions found <a href="https://customercare.23andme.com/hc/en-us/articles/360034119874-Adding-2-Step-Verification-to-Your-23andMe-Account">here</a>. 



<h6 class="wp-block-heading" id="h-questions">Questions?</h6>



As always, customers can work with our <a href="https://customercare.23andme.com/hc/en-us/">Customer Care team</a> if they have questions about using this added security step.



 This new security update is part of our ongoing commitment to keep customer data safe and secure. It’s another line of defense to protect their data. We encourage all of our customers to review our <a href="https://customercare.23andme.com/hc/en-us/articles/360062175913-Privacy-and-Security-Help-Center">Privacy and Security Checkup</a> page, where they will find additional information on how to keep their accounts secure.

Enhanced Customer Security at 23andMe with 2-Step Verification

Update: December 5, 2023 2:45 PM PST



<h2 class="wp-block-heading" id="h-credential-stuffing-incident-what-happened">Credential Stuffing Incident: What happened?</h2>



As our investigation comes to a close, we wanted to share the details of what took place and our findings.&nbsp;



In early October, we learned that a threat actor accessed a select number of individual 23andMe.com accounts through a process called credential stuffing. That is, usernames and passwords that were used on 23andMe.com were the same as those used on other websites that have been previously compromised or otherwise available. We do not have any indication that there was a data security incident within our systems, or that 23andMe was the source of the account credentials used in these attacks.&nbsp;



The threat actor used the compromised accounts to access information shared with these accounts. Specifically, DNA Relatives profiles connected to these compromised accounts, which consist of information that a customer chooses to make available to their genetic relatives when they opt in to participate in 23andMe’s DNA Relatives feature. A DNA Relatives profile includes information such as display name, predicted relationships, and percentage of DNA shared with matches. You can find a full list of the types of information included in a DNA Relatives profile <a href="https://customercare.23andme.com/hc/en-us/articles/212170838">here</a>.



Additionally, through the compromised accounts, the threat actor accessed a feature called Family Tree, which includes a limited subset of DNA Relatives profile information. The Family Tree feature does not include ancestry information such as the percentage of DNA shared with genetic matches or ancestry reports.



<h2 class="wp-block-heading" id="h-what-the-threat-actor-accessed-nbsp">What the Threat Actor Accessed&nbsp;</h2>



<ul class="wp-block-list">
<li>The threat actor was able to access less than 0.1%, or roughly 14,000 user accounts, of the existing 14 million 23andMe customers through credential stuffing.&nbsp;</li>



<li>The threat actor used the compromised credential stuffed accounts to access the information included in a significant number of DNA Relatives profiles (approximately 5.5 million) and Family Tree feature profiles (approximately 1.4 million), each of which were connected to the compromised accounts.</li>
</ul>



Since detecting the incident, we emailed all customers to notify them of the investigation and are continuing to notify impacted customers, based on applicable laws. We also required every 23andMe customer to reset their password. In addition, 23andMe now requires all new and existing customers to login using two-step verification. Protecting our customers’ data privacy and security remains a top priority for 23andMe, and we will continue to invest in protecting our systems and data.



<hr class="wp-block-separator has-alpha-channel-opacity"/>



<h2 class="wp-block-heading" id="h-security-incident-updates">Security Incident Updates</h2>



Update: December 1, 2023 3:45 PM PST



23andMe has completed its investigation, assisted by third-party forensics experts. We are in the process of notifying affected customers, as required by law.&nbsp;



We have taken steps to further protect customer data, including requiring all existing customers to reset their password and requiring two-step verification for all new and existing customers. The company will continue to invest in protecting our systems and data.



<hr class="wp-block-separator has-alpha-channel-opacity"/>



Updated: November 6, 2023 7:45 AM PST



Starting today, we are requiring all customers to utilize email 2-step verification (2SV) as an&nbsp;added&nbsp;layer of protection for their account.&nbsp;New customers will be automatically enrolled in email 2SV when they create their account. Existing customers who do not already use an authenticator app will also be automatically enrolled in email 2SV, and will receive an email containing their verification code at their next sign-in. You can read <a href="https://blog.23andme.com/articles/enhanced-customer-security-at-23andme-with-2-step-verification">more on our blog post</a>.



Update: October 20, 2023 9:35 PM PST



As part of the ongoing security investigation, we have temporarily disabled some features within the DNA Relatives tool as an additional precaution to protect the privacy of our customers.



<hr class="wp-block-separator has-alpha-channel-opacity"/>



<h2 class="wp-block-heading" id="h-what-actions-has-23andme-taken">What actions has 23andMe taken?</h2>



Update: October 9, 2023 8:25 PM PST



Our investigation continues and we have engaged the assistance of third-party forensic experts. We are also working with federal law enforcement officials.&nbsp;



We are reaching out to our customers to provide an update on the investigation and to encourage them to take additional actions to keep their account and password secure. Out of caution, we are requiring that all customers reset their passwords and are encouraging the use of multi-factor authentication (MFA).



If we learn that a customer’s data has been accessed without their authorization, we will notify them directly with more information.



Please continue to follow this blog for updates as our investigation continues



<hr class="wp-block-separator has-alpha-channel-opacity"/>



October 6, 2023



<h2 class="wp-block-heading" id="h-credential-stuffing-attack">Credential Stuffing Attack</h2>



We recently learned that certain 23andMe customer profile information that they opted into sharing through our <a href="https://customercare.23andme.com/hc/en-us/articles/212170838">DNA Relatives feature</a>, was compiled from individual 23andMe.com accounts without the account users’ authorization.



After learning of suspicious activity, we immediately began an investigation.&nbsp; While we are continuing to investigate this matter, we believe threat actors were able to access certain accounts in instances where users recycled login credentials – that is, usernames and passwords that were used on <a href="https://www.23andme.com/">23andMe.com</a> were the same as those used on other websites that have been previously hacked. 



We believe that the threat actor may have then, in violation of our <a href="https://www.23andme.com/legal/terms-of-service/#requirements-and-conditions">Terms of Service</a>, accessed <a href="https://www.23andme.com/">23andMe.com</a> accounts without authorization and obtained information from certain accounts, including information about users’ DNA Relatives profiles, to the extent a user opted into that service.&nbsp;



<h2 class="wp-block-heading" id="h-committed-to-safety-and-security">Committed to Safety and Security</h2>



23andMe is committed to providing you with a safe and secure place where you can learn about your DNA knowing your privacy is protected. We are continuing to investigate to confirm these preliminary results. We do not have any indication at this time that there has been a data security incident within our systems, or that 23andMe was the source of the account credentials used in these attacks.&nbsp;



At 23andMe, we take security seriously. We exceed industry data protection standards and have achieved three different ISO certifications to demonstrate the strength of our security program.&nbsp; We actively and routinely monitor and audit our systems to ensure that your data is protected.&nbsp; When we receive information through those processes or from other sources claiming customer data has been accessed by unauthorized individuals, we immediately investigate to validate whether this information is accurate. Since 2019 we’ve offered and encouraged users to use multi-factor authentication (MFA), which provides an extra layer of security and can prevent bad actors from accessing an account through recycled passwords.



<h2 class="wp-block-heading" id="h-recommendations">Recommendations </h2>



We encourage our customers to take as much action to keep their account and password secure. Out of caution, we recommend taking the following steps:



<ul class="wp-block-list">
<li>Confirm you have a strong password, one that is not easy to guess and that is unique to your 23andMe account. If you are not sure whether you have a strong password for your account, reset it by following the steps outlined <a href="https://customercare.23andme.com/hc/en-us/articles/202907580-Forgot-Your-Password-#:~:text=You%20are%20able%20to%20reset,the%20Send%20Reset%20Email%20button.">here</a>.&nbsp;</li>



<li>Please be sure to enable multi-factor authentication (MFA) on your 23andMe account. You can enable MFA by following the steps outlined <a href="https://customercare.23andme.com/hc/en-us/articles/360034119874-Adding-2-Step-Verification-to-Your-23andMe-Account">here</a>.</li>

The findings firm up a long-suspected connection between migraines and blood sugar regulation. Migraines affect greater than<a href="https://jamanetwork.com/journals/jama/fullarticle/2787727#:~:text=Migraine%20affects%20an%20estimated%20more,in%20women%20than%20in%20men."> 10 percent of the world population</a>. Women are more than three times more likely to experience migraines than men.



“As far back as 1935, migraine was described as a ‘glycemic headache’,” said Dale Nyholt, professor at the Australia’s Queensland University of Technology<a href="https://www.qut.edu.au/research/centre-for-genomics-and-personalised-health" target="_blank" rel="noreferrer noopener"> Centre for Genomics and Personalised Health</a>. “Glycemic traits such as insulin resistance, hyperinsulinemia (too much insulin), hypoglycemia (low blood sugar level) and type 2 diabetes are associated with migraine and headache.”



<h6 class="wp-block-heading">Understanding the Link</h6>



The genetic overlap of those traits helps scientists better understand how migraines and blood sugar may be related. It may also help scientists studying the best way to treat the condition. The link between migraines and blood sugar has been known. However, this is the first time researchers could see a genetic link between the two, Nyholt said.



Researchers at the Australia’s Queensland University of Technology led the study. It looked at data from more than a dozen institutions including from 23andMe. In all, data from almost 900,000 individuals was included in the study. About 100,000 of those individuals were 23andMe customers who consented to participate in research.

Genetic Links Between Migraines and Blood Sugar

If even the idea of a boat trip triggers a bit of nausea, you may be able to partly blame it on your genetics.
23andMe scientists have identified more than 413 genetic variants associated with motion sickness — that queasy feeling some of us get riding in cars, planes or traveling on the sea.
23andMe now offers a report on a customer’s genetic predisposition for motion sickness. Using data from more than 480,000 customers who’ve participated in research, 23andMe’s new report analyzes a customer’s genetic data against variants associated with motion sickness. On top of using genetic factors the report also takes into account non-genetic factors such as a customers age, sex, and ancestry, and then reports back whether a customer is more or less likely to experience motion sickness.

The sensation comes, in part, from one’s body trying to maintain balance. To keep our balance, we all rely on signals from multiple sources, both visual and physical, as well as signals from the vestibular system in our inner ear. When those sensory signals conflict — say our vision tells us we are sitting still, but we can feel ourselves moving in a car or on a boat — it can trigger feelings of nausea or dizziness. A person’s genetics may make them more or less susceptible to feeling motion sickness.
While seemingly trivial, it’s not for those who experience severe cases. And motion sickness has been found to be associated with several other more serious conditions. 23andMe previously published a<a href="https://academic.oup.com/hmg/article/24/9/2700/2385879"> study</a> that confirmed associations with such conditions as migraines, vertigo, and morning sickness.
This report, as well as the now more than two-dozen<a href="https://www.23andme.com/dna-health-ancestry/#toc-traits"> other trait reports</a> we offer within the <a href="https://www.23andme.com/dna-health-ancestry/"> Health + Ancestry</a> Service, are meant to give customers a bit more insight into the fascinating world of genetics. They also add to the understanding of how your DNA and environment interact to help influence all the many things that are part of who you are.

Feeling Woozy Over 23andMe’s New Report on Motion Sickness

Starting today, we&#8217;re providing an easy way for our customers to share and crowdsource treatments they use to manage common health conditions, like depression, asthma, <a href="https://blog.23andme.com/articles/new-23andme-report-on-attention-deficit-hyperactivity-disorder">ADHD</a> and migraine.
<h6>Conditions Pages</h6>
All 23andMe Health + Ancestry service customers will be able to learn about the effectiveness and popularity of hundreds of different treatments for common conditions — and will also be able to contribute their own personal experiences. Crowdsourced treatment ratings are just one facet of our new <a href="https://you.23andme.com/research/condition/">Condition Pages</a>, which contain database insights on 18 <a href="https://blog.23andme.com/articles/23andme-adds-another-important-condition-to-health-communities">common health conditions</a>.
Each condition page includes scientifically curated information describing the condition, its genetic and non-genetic influences, as well as how common it is in 23andMe research participants.
<img loading="lazy" decoding="async" class="aligncenter wp-image-26135 size-full" src="http://35.88.189.111/wp-content/uploads/2018/04/Conditions-PageDepression.jpg" alt="An image from the health conditions page showing results around depression." width="890" height="681" srcset="https://blog.pub.us-west-2.prd.23andme.us/wp-content/uploads/2018/04/Conditions-PageDepression.jpg 890w, https://blog.pub.us-west-2.prd.23andme.us/wp-content/uploads/2018/04/Conditions-PageDepression-300x230.jpg 300w, https://blog.pub.us-west-2.prd.23andme.us/wp-content/uploads/2018/04/Conditions-PageDepression-768x588.jpg 768w, https://blog.pub.us-west-2.prd.23andme.us/wp-content/uploads/2018/04/Conditions-PageDepression-880x673.jpg 880w" sizes="auto, (max-width: 890px) 100vw, 890px" />
The treatment section summarizes what 23andMe customers with these conditions say works or does not work in treating their condition.
<h6>Treatments Page</h6>
This kind of crowd-sourced tool allows individuals with say, depression, to see what other customers say is effective or not effective in treating the condition. This offers people a different kind of information than they could get simply by doing a Google search, because it comes from others like them living with the same conditions.
Since rolling out the treatment pages over the past few weeks, thousands of people have already contributed over 30,000 personal reviews of their responses to different treatments. This is allowing people to <a href="https://blog.23andme.com/articles/23andme-adds-another-important-condition-to-health-communities">build communities</a> that share common conditions but have different strategies for dealing with them. At 23andMe, we believe in helping our customers manage their health — not just through <a href="https://www.23andme.com/dna-health-ancestry/">genetic reports</a>, but also by giving them access to lots of useful, relevant information.
“It’s evident by the growing response from our customers that there is a real desire for information around health treatments,” says Jessie Inchauspe, the product manager who spearheaded work on the treatment pages. “It’s important to enable people to actively engage in sharing health information with each other.”
This is the first time we’ve enabled customers to share real-time health information with one another.
<img loading="lazy" decoding="async" class="aligncenter wp-image-26134 size-large" src="https://blog-api.23andme.com/wp-content/uploads/2018/04/Treatment-effectivenss-1024x946.jpg" alt="A page from the health conditions feature that shows an example of how people report what they do for their depression including using medication and exercise and how they rate its effectiveness." width="1024" height="946" srcset="https://blog.pub.us-west-2.prd.23andme.us/wp-content/uploads/2018/04/Treatment-effectivenss-1024x946.jpg 1024w, https://blog.pub.us-west-2.prd.23andme.us/wp-content/uploads/2018/04/Treatment-effectivenss-300x277.jpg 300w, https://blog.pub.us-west-2.prd.23andme.us/wp-content/uploads/2018/04/Treatment-effectivenss-768x710.jpg 768w, https://blog.pub.us-west-2.prd.23andme.us/wp-content/uploads/2018/04/Treatment-effectivenss-880x813.jpg 880w, https://blog.pub.us-west-2.prd.23andme.us/wp-content/uploads/2018/04/Treatment-effectivenss-1180x1090.jpg 1180w, https://blog.pub.us-west-2.prd.23andme.us/wp-content/uploads/2018/04/Treatment-effectivenss.jpg 1554w" sizes="auto, (max-width: 1024px) 100vw, 1024px" />
For example, you can see here the most <a href="https://blog.23andme.com/articles/what-patients-say-works-for-bipolar-disorder">effective treatments for depression</a> reported by 23andMe customers. These include therapy, exercise, and antidepressants such as Zoloft and Wellbutrin.
<h6>Crowdsourced Information</h6>
You can also see what treatments could potentially lead to worse outcomes. For example, based on the data shared for asthma, inhalers were among the most used and most effective treatment, but they also included some cases where the symptoms got worse. However, “avoiding allergens” was a relatively effective approach without any potential negative effects.
Many treatments are designed for the average patient in mind, but few of us are actually average. We are each unique, and understanding those differences — even small ones — is essential to learn how to better treat conditions and make medical care more personalized. Genetics certainly offers important insight into how we differ in response to treatments. Allowing people to have a place to share their own experience will also aid in our understanding.
For now, the purpose of these pages is to share this crowdsourced information on the effectiveness of treatments. But the information could at some people aid in research into how people of different ethnicities or different genetic makeups respond differently to treatments.

Crowdsource Treatments for Health Conditions

In the largest-ever <img loading="lazy" decoding="async" class="alignright size-medium wp-image-19308" src="https://blog-api.23andme.com/wp-content/uploads/2013/09/Migraine-Photo-200x300.jpg" alt="Migraine Photo" width="200" height="300" srcset="https://blog.pub.us-west-2.prd.23andme.us/wp-content/uploads/2013/09/Migraine-Photo-200x300.jpg 200w, https://blog.pub.us-west-2.prd.23andme.us/wp-content/uploads/2013/09/Migraine-Photo.jpg 566w" sizes="auto, (max-width: 200px) 100vw, 200px" />with these sometimes debilitating headaches that are estimated to affect as many as a billion people worldwide.
<h2>Genetic Associations &amp; Vascular Dysfunction</h2>
Along with identifying 44 variants associated with migraines, the findings also point to vascular dysfunction as one of the biological underpinnings for the disease. Researchers have debated for years whether vascular or neuronal dysfunction could explain a propensity for migraines. This study provides the first genetic evidence pointing to vascular dysfunction as a potential cause.
“We provide evidence that migraine-associated genes are involved both in arterial and smooth muscle function,” the researchers wrote. “These results suggest that vascular dysfunction and possibly also other smooth muscle dysfunction likely play roles in migraine pathogenesis.”

<h2>What Are Migraines?</h2>
Migraines often involve debilitating pain that can last many hours, or, in some cases, days. Beyond the pain, the symptoms can trigger nausea, vomiting, and, for some who suffer from migraines with auras, distorted vision, or flashes of light. This subtype of migraine includes symptoms that often occur before a migraine starts, where those with the condition report having blind spots in their vision or seeing bright lights or other patterns.
Although the researchers looked, they could not detect any genetic associations that would differentiate the two types of migraines.
The 44 genetic variants they identified are located in 38 genes or gene regions, and many of those loci are involved in regulating vascular tissue and soft muscle tissue, such as that found inside blood vessel walls. Of the genetic variants associated with migraines, 28 were identified for the first time.
<h2>Risks Associated with Migraines</h2>
These findings are consistent with research that shows that individuals who suffer from migraines are at a higher risk for stroke and cardiovascular disease. Interestingly, the researchers also found that the same genetic variant in the PHACTR1 gene that is associated with risks for a tear in arteries in the neck – a phenomenon called Cervical Artery Dissection that is a common cause of strokes for people under 50 – is also associated with migraines.
The study&#8217;s researchers, published this week in the journal Nature Genetics, performed a meta-analysis that gathered 22 different genome-wide association studies and included data from more than 375,000 individuals worldwide.
About 173,000 of those individuals are 23andMe customers who consented to research. The 23andMe cohort was by far the largest used by the researchers. Much of the other data was collected together by the<a href="http://www.headachegenetics.org/"> International Headache Genetics Consortium</a> and included contributions from researchers in the UK, Iceland, Finland, Germany, the Netherlands, Australia and Estonia. This work also follows a study done by the consortium.
&#8220;We simply can’t overstate the importance of international collaboration when studying the genetics of complex, common diseases,&#8221; said Palotie, who heads up the International Headache Genetics Consortium and works as a Research Director at the Institute for Molecular Medicine Finland, University of Helsinki, as well as serving as an associate member at the Broad Institute of MIT and Harvard.
The researchers said the findings from this study could be a first step in developing new treatments for migraines.
The study can be found in the journal <a href="https://www.nature.com/ng/journal/v48/n8/full/ng.3598.html">Nature Genetics.</a>

The role of genetics in migraines

We’re feeling a little dizzy trying to keep track of all the coverage 23andMe’s new study on motion sickness received or it might just be this infographic.


The<a href="http://hmg.oxfordjournals.org/content/early/2015/01/26/hmg.ddv028.abstract?keytype=ref&#038;ijkey=2ntxck5YUKc8QSA"> paper</a>, which came out in late January, was the first ever genome-wide association study of the very common condition.
We want to share with you some of the better stories, including coverage in<a href="https://www.fastcompany.com/3042008/feeling-woozy-23andme-releases-first-ever-genome-wide-study-of-motion-sickness"> Fast Company</a>, the<a href="http://www.theatlantic.com/health/archive/2015/02/the-mysterious-science-of-motion-sickness/385469/"> Atlantic</a> and<a href="https://time.com/3695231/23andme-motion-sickness/"> Time</a>. We also wanted to share some of the findings in the study using this fun infographic.
In the study, 23andMe researchers found 35 genetic variants that were significantly associated with motion sickness. Some of those variants, which were identified for the first time, are in or near genes involved in the development of the eye and ear, while other variants appear to be involved in neurological processes and the regulation of glucose and insulin.
The work also confirmed previously known phenotypic associations between motion sickness and other conditions such as migraines, vertigo, and morning sickness as well as postoperative nausea and vomiting.

Feeling Woozy, Motion Sickness Redux

If a bumpy ride in the back of a car makes you nauseated, blame it on your genetics, according to the first ever genome-wide association study <img loading="lazy" decoding="async" src="https://blog-api.23andme.com/wp-content/uploads/2014/09/Bethann-Hromatka-2-253x300.jpg" alt="Bethann Hromatka 2" class="alignright size-medium wp-image-21548" width="253" height="300" />


Motion sickness is extremely common. One in three of us is highly susceptible to it, and the condition is very heritable. That means that genetics accounts for a large reason why some of us are more prone to motion sickness than others. 
<h6>Current Estimates</h6>
Estimates indicate that most of a person’s risk for experiencing motion sickness is pegged to their genetics. Motion sickness also tends to be more common in women and younger people.
But even with what we know about the condition, and how common it is, we still don’t fully understand its underlying causes.
New research by 23andMe may change that.
23andMe researchers conducted the first genome-wide association study on motion sickness and found 35 genetic variants that were significantly associated with the condition. Published in Oxford Journals’ <a href="http://hmg.oxfordjournals.org/content/early/2015/01/26/hmg.ddv028.abstract?keytype=ref&#038;ijkey=2ntxck5YUKc8QSA" target="_blank" rel="noopener noreferrer">Human Molecular Genetics</a>, this study is the first to identify the genetic variants associated with this highly heritable condition.
“It’s estimated that up to 70 percent of a person’s risk for motion sickness is due to genetics, but up until now the genetics of motion sickness was poorly understood,” said 23andMe Scientist Bethann Hromatka, one of the study’s authors. “We’ve identified 35 genetic associations with motion sickness that fall into a few different biological categories. Some genetic variants are in or near genes involved in development, including development of the eye and ear. Other variants appear to be involved in neurological processes as well as glucose and insulin regulation.”

<h6>Previous Known Phenotypes</h6>

The study, which involved the consented participation of more than 80,000 23andMe customers, also gives us new insight into the biology of the condition. The work also confirmed previously known phenotypic associations between motion sickness and other conditions such as migraines, vertigo, and morning sickness as well as postoperative nausea and vomiting.


These findings could help provide many new clues about the causes of motion sickness and other related conditions.
Because the study also identified associations between motion sickness and lifestyle the new findings could help researchers identify risk factors  and future treatments.  They know for instance that there is an association between being a poor sleeper and having a propensity for motion sickness. 
The researchers also note that experiencing headaches after drinking red wine is associated with a propensity toward motion sickness. In addition having a good sense of direction and the ability to handle stress are also associated with having a lower risk for motion sickness. While these are all interesting findings, it is difficult to assess causality. For example, does being a sound sleeper make one less susceptible to being motion sick, or vice versa. Or are both related to a third condition?

Genetics found to influence likelihood of motion sickness

Eight of the top ten patient-reported treatments for Migraine are simple lifestyle changes, not drugs. CureTogether – a free resource owned by 23andMe that allows people to share information about their health and treatments – surveyed more than 6,000 people who self-identify as having Migraine. They reported that interventions such as sleeping in <img loading="lazy" decoding="async" class="alignright size-thumbnail wp-image-19308" alt="Migraine Photo" src="https://blog-api.23andme.com/wp-content/uploads/2013/09/Migraine-Photo-200x200.jpg" width="293" height="293">a dark, quiet room, avoiding smoke and red wine, and using ice packs helped them feel better.
Migraine can involve debilitating pain for many hours or days, sometimes interfering with work and day-to-day activities. Participants in the study said they found that prescription medications like Imitrex, Treximet, and DHE, as well as relaxation, hydration, <a href="https://www.23andme.com/topics/wellness/caffeine-consumption/">caffeine</a>, and exercise were among the most effective treatments. The survey also found that some common treatments such as alcohol, contraceptive pills, headstands, Paxil and Effexor XR actually made the symptoms of Migraine worse. 
 
The Migraine Research Foundation estimates that over ten percent of the population, including children, suffers from Migraine, with a frequency ranging from once a month to every day. Nearly one in four US households has a Migraine sufferer in it. The condition can be extremely painful and is not well

understood, and finding accurate recommendations on treatments that work well can be challenging, so CureTogether asked people who experience Migraine to rate the effectiveness of 204 different patient-reported treatments.
Where did this data come from? This is the result of a four-year CureTogether study on <a href="http://curetogether.com/migraine/symptoms/">Migraine</a>, in which 6,259 people shared information about their symptoms and what treatments worked best for them. We’d like to thank those who participated. And just as they shared their experience with treatments, we’re freely and openly sharing the results of the Migraine study.
This is part of a regular series of CureTogether <a href="http://curetogether.com/blog/category/research-findings/">research findings</a>. CureTogether’s research findings are different than 
associations with illness, traits and drug response. But as we continue our work with the CureTogether community, 23andMe hopes to incorporate more of this kind of self-reported information into our own

What Patients Say Works (And Doesn’t) for Migraines

By Robin Smith, Health Content Scientist at 23andMe
<img loading="lazy" decoding="async" class="alignright size-full wp-image-18305" title="Yasmina.Bounty" src="https://blog-api.23andme.com/wp-content/uploads/2013/05/Yasmina.Bounty.jpg" alt="" width="295" height="240" />Image courtesy of <a href="https://blog-api.23andme.com/wp-content/uploads/2013/05/Yasmina.Bounty.jpg">Wikimedia Commons</a>.
In January of 1790, a small band of mutineers from the HMS Bounty evaded capture by the British Navy and settled Pitcairn Island in the South Pacific.
The direct descendants of this crew (and their captive Tahitian &#8220;wives&#8221;) now number in the thousands on nearby Norfolk Island, where the colony relocated in 1856. Detailed records on Norfolk have been used to construct an elaborate family tree of 6,500 individuals spanning 12 generations, all originating from just 17 colonists.
<h6 dir="ltr">Bottleneck Populations</h6>
Bottlenecked populations such as this one are of great interest to geneticists, as they can be used to test ideas about the heritability of common diseases. Modern-day Norfolk Islanders are particularly susceptible to migraines: debilitating headaches that often occur only on one side of the head and can be accompanied by nausea, sensitivity to light and sound, and other vision problems.
Norfolk Islanders are more than twice as likely to suffer from migraines as Caucasians in Europe and North America (25.5 percent vs. 12 percent) and the condition is clearly inherited within families.
<h6>Migraines</h6>
Although migraines have been linked to environmental triggers such as caffeine withdrawal and monosodium glutamate (MSG) consumption, the genetic factors that influence them have only recently begun to emerge. The <a href="http://www.headachegenetics.org/">International Headache Genetics Consortium (IHGC)</a> reported a <a href="https://dx.doi.org/10.1038/ng.2307">study</a> in the journal Nature Genetics in which a healthy cohort of 4,580 individuals was compared to 2,326 patients afflicted with the most common form of migraines. The IHGC study identified multiple risk regions encompassing genes that play key roles in the development of neurons and the formation of synapses in the brain.
The study found an association between the marker SNP and susceptibility to migraines. Each copy of a &#8220;C&#8221; at this position increases the odds of migraine by 20 percent.
<a href="https://dx.doi.org/10.1038/ng.856">Previous research</a> by the same group identified three SNPs associated with migraine susceptibility. These markers are thought to indicate the function of a sensor protein involved in neuropathic pain, as well as a gene that regulates levels of the neurotransmitter glutamate.

The underlying cause of the migraines on Norfolk Island remains elusive. A recent <a href="https://www.ncbi.nlm.nih.gov/pubmed/22678113">study</a> in the journal Neurogenetics suggested a link with variants near genes that regulate serotonin levels. One of many neurotransmitters, serotonin is a messaging molecule produced by specialized brain cells and influences a wide range of human behavior, including appetite, sleep, memory, and mood.
The finding in Norfolk Islanders is consistent with studies showing serotonin imbalances in people suffering from migraines. Moreover, a class of drugs named triptans mimic serotonin and has proven useful in combating the acute effects of migraines. Further study of the unique population on Norfolk Island will hopefully shed more light on this pathway and help to discover new risk factors for migraines.
