New genetic risk factor for type 2 diabetes revealed

An international team of researchers in Mexico and the United States has uncovered a new genetic clue that contributes to an increased risk of developing type 2 diabetes, particularly the elevated risk among Mexican and other Latin American populations.

The team, known as the SIGMA (Slim Initiative in Genomic Medicine for the Americas) Type 2 Diabetes Consortium, performed the largest genetic study to date in Mexican and Mexican American populations, discovering a risk gene for type 2 diabetes that had gone undetected in previous efforts. People who carry the higher risk version of the gene are 25 percent more likely to have diabetes than those who do not, and people who inherited copies from both parents are 50 percent more likely to have diabetes.
