SNPwatch: Largest Alzheimer’s Genetic Studies To Date Identify Three New Susceptibility Genes

Despite years of effort and millions of dollars in research funding, only one gene, APOE, has been conclusively associated with Alzheimer's disease risk so far.  But now the results of two of the largest Alzheimer's studies ever provide convincing evidence that three more genes affect risk for the ...

Surprisingly Skinny Mice Could Point the Way to Obesity and Diabetes Treatments

Scientists who are studying mice with a mutation that makes them resistant to obesity even in the face of a high-fat diet may have identified a new way to treat both obesity and diabetes. Carrying extra weight is known to trigger a state of chronic, low-grade inflammation in the body, which can lead to ...

What Makes Us Human? Study Finds Hints By Comparing Chimp and Human DNA

We may be another step closer to discovering what makes us human. A new study published online this week in Genome Research has pinpointed three genes in humans that may genetically differentiate us from chimps and other primates. Genetically we are very similar to chimps, so most of the differences ...

New Study on Genetics of Ethnic Groups Reveals We May Not Be So Different After All

There are many examples around the world of two distinct ethnic groups living side by side. Sometimes these groups co-exist peacefully. Other times they do not. Often two groups' differences - along with circumstantial factors - lead to tension between them and sometimes violence. The Hutus and Tutsis ...

SNPwatch: Genetic Variation Associated With Addiction In Caucasian Women

Although environment plays a major part in addiction — you can't get hooked on something you've never tried — genetics plays a substantial role in determining whether a person who does use a drug will become addicted to it. A few DNA variations have been identified that seem to increase the odds a person ...

Study Sniffs Out Genes Behind Doggy ‘Dos

New genetic research may explain why Fluffy is so fluffy. A study led by researchers at the National Human Genome Research Institute scanned 1,000 dogs from 80 breeds, looking for genes associated with different hair types: curly, wavy, straight, wiry, long and any combination of these. Their results, ...

More Evidence that Genetics Can Reduce the Efficacy of Anti-Clotting Medication Clopidogrel

A new report in the Journal of the American Medical Association adds to the mounting evidence that genetic variations impact the efficacy of clopidogrel (Plavix®), a drug used to prevent blood clots in people who have had a heart attack or stroke and also those with peripheral artery disease and unstable ...

Very Personalized Medicine: Sequencing of Second Cancer Patient Reveals Potentially Significant Mutations

A new genetic screening process has helped researchers understand the genetic causes of cancer, such as how mutations accumulated in a person's life can cause leukemia. The study shows that by comparing a person's own DNA to that of their cancerous cells, researchers can find DNA mutations that may have ...

On Finding Needles in Genetic Haystacks

Nearly a year ago today, the Spittoon reported that researchers had figured out how to pick a known person's DNA out of a database containing genetic information for up to 200 unidentified individuals. The feat made it possible to determine, for example, if a particular suspect's DNA was present in a mix of ...
