Don't Take it Personal...,

In the last several months a potential new tool for diabetes prevention has come to market. A test developed by the Icelandic genomics company deCode Genetics and marketed to consumers by San Francisco-based DNA Direct determines whether people carry copies of a genetic variation that can greatly increase the risk of developing type 2 diabetes. Diabetes is the result of a complex mix of genetic and environmental factors. But recent genomic studies have identified several genetic variations that contribute heavily to the disease. The one that exerts by far the biggest influence occurs in a gene called TCF7L2, which was discovered by scientists at deCode in 2005; almost 20 percent of people with type 2 diabetes carry two copies of the high-risk version of the gene. These people are thought to secrete less insulin, a crucial hormone that signals cells to store glucose for energy. A single copy of the varia­tion somewhat increases the risk of contracting the disease, and two copies double the risk, regardless of other risk factors.

The Genetic Information Non-Discrimination Act, which would prohibit discrimination in employment or insurance on genetic grounds, is still lounging in the Senate, despite presidential support and a whopping margin (420-3) in the House of Representatives.

Do you really imagine that there's anything about you that "our" governing aristocrats consider inviolable?

Remember, what, it's all about...,
