New Study Argues For Construction of Mexican Medical Genetic Reference Database

Mexican flu virus genetics has been much in news lately; how about a look at Mexican human genetics for a change? A new article from researchers at Mexico's National Institute for Genomic Medicine (INMEGEN) examines genetic diversity across the nation, and argues that, in order to conduct studies of common ...

328 Genomewide Association Studies and Counting … What Now?

In 2005 two well-known human geneticists, Francis Collins and Thomas Gelehrter, made a bet: Collins wagered that by the 2008 American Society for Human Genetics meeting, genomewide association studies would have led to the discovery of at least four “validated - not just guessed at” susceptibility variants ...

Baby, It’s Cold Outside: Researchers Tie Variation in Cancer Gene to Winter Temperatures

How can geneticists tell when a genetic difference between two human populations is an accident and when it’s the result of natural selection? As our species moved out of Africa and spread out across the globe, there were a lot of chances for random DNA mutations to occur.  Many of these were neutral – ...

How A Person Smokes Might Affect Lung Cancer Risk

For many common diseases, environment is far more important than genetics in determining whether a person will be affected. One of the best examples of this is lung cancer. Nearly 90% of the cases of this disease can be attributed to smoking. Today at the American Association for the Advancement of  ...

New Papers from Nature Genetics Yield a Bounty of Cholesterol SNPs

SNPwatch gives you the latest news about research linking various traits and conditions to individual genetic variations. These studies are exciting because they offer a glimpse into how genetics may affect our bodies and health; but in most cases, more work is needed before this research can provide ...

A Genomic Moment

Russ Altman. In a recent post on his "Building Confidence" blog, 23andMe scientific advisor Russ Altman recounts an experience that should be familiar to 23andMe customers who regularly read The Spittoon. After reading a recent New England Journal of Medicine paper about a genetic variant associated with ...

Researchers Find Biological Basis For Crohn’s Association

Just about every week a new genome-wide association study links common variations in the genome to some disease. But only rarely do the authors of these studies have more than a guess of why these SNPs are associated with a particular condition. On Sunday in the online edition of Nature Genetics, ...

The Ultimate Trade-off: Genes, Environment, and Why We Crave Twinkies

Last week in the Spittoon we reported on a new study that identified an interesting genetic trade-off — a genetic variant known that has one effect on a person's vulnerability to malaria, and the opposite on susceptibility to HIV infection. The "Duffy negative" version of the gene, which is common among ...

Why Ancestry Makes a Difference

Those of you who have delved into our Gene Journal (now called Health and Traits) feature may have noticed that many of the traits only give genetic data “assuming European ethnicity”. Why is that? It certainly isn’t because people with African or Asian ancestry aren’t susceptible to heart attacks or ...
