SNPwatch: Two Large Studies Identify More Variants Associated with Blood-Related Traits

Previously in The Spittoon, we discussed two papers that identified genetic variants associated with hemoglobin levels in circulating blood. But blood consists of much more than hemoglobin, and it is responsible for much more than just transporting oxygen. This week Nature Genetics published the results of ...

23and¡Mi Cabeza!: A New Migraine Headache Survey

Here’s how it goes for me: a few afternoons a year, usually when I haven’t slept or eaten right, but sometimes for no apparent reason, I begin to sense a pressure behind my left eyebrow and to feel queasy. By now I know what’s coming, and I resign myself to another miserable evening and a coming day or two ...

SNPwatch: Genetic Variations Influencing Hemoglobin Levels Identified

Doctors routinely order the complete blood count (CBC) for their patients because they can learn a lot about a person's health by measuring the numbers of different types of blood cells in the circulation, their sizes and the ratios between them. One component of the CBC is usually a measure of the total ...

SNPwatch: The Plot Thickens For Thinning Bones

Our bones are amazing structures, capable of supporting tremendous force through complex motions. They do this day in and day out, year after year as we sit, stand, walk, run, lift, work, and play. But as the elderly among us know all too well, bones are not invincible and become more fragile as we age. As ...

SNPwatch: Genetic Clues to Bowel Disease Found in Mice and Men

Inflammatory bowel disease (IBD), which can appear as either ulcerative colitis or Crohn's disease, damages the lining of the digestive tract and leads to abdominal cramps, incomplete digestion and nutritional deficiencies. Previous research on IBD gave researchers reason to suspect that the CD39 gene, ...

SNPwatch: Researchers Find More Genetic Variants Associated With Prostate Cancer

In the United States, prostate cancer affects about one in every six men.  Genomewide association studies aimed at finding common genetic variants associated with this common disease have been particularly successful. More than a dozen SNPs have been associated with prostate cancer, but researchers calculate ...

SNPwatch: Common Variants May Influence Glaucoma Risk in Individuals of African Descent

Editor’s note: Pending an FDA decision, 23andMe no longer offers new customers access to health reports referred to in this post. Customers who purchased prior to November 22, 2013 will still be able to see their health reports, but those who purchased after that time will not. Those customers will have ...

SNPwatch: Evidence for Gene-Environment Interaction in Alcoholism

Addiction to alcohol is associated with the brain’s reward system, which reinforces behaviors that feel good — like drinking — by releasing neurotransmitters such as dopamine and endorphins. With prolonged alcohol consumption, a person's brain can gradually adapt to the point that excessive amounts of ...

SNPwatch: More Evidence That Genetic Variations are Important for Hepatitis C Infection and Treatment

Unlike the flu virus, which the body is generally able to fight off completely, infection with hepatitis C is often chronic.  That means for most of the three to four million people worldwide who are newly infected each year the virus will persist in the body, where it greatly increases risk for chronic ...

SNPwatch: Genetic Flaw that Causes Rare Metabolic Condition May Also Increase Risk of Severe Liver Disease in Cystic Fibrosis

New research suggests the primary genetic mutation that causes alpha-1 antritrypsin deficiency, a condition that results in liver damage and a wide variety of other problems, also affects risk for liver disorders associated with cystic fibrosis. Cystic fibrosis is an inherited, childhood-onset disorder ...
