We know type 1 diabetes is as much affected by genes as it is by lifestyle and environment. But a huge international study found that there could be as many as 41 genetic loci that affect the risk of type 1 diabetes!
Touted as the largest genetic study into type 1 diabetes, and published in Nature Genetics online this week, the study combined results from two previous studies and found 41 genomic locations were significantly associated with diabetes. The DNA of more than 10,000 people with diabetes from all over the world were studied, including more than 2,300 families with at …read more

There is no doubt that obesity is primarily caused by poor eating habits and inactive lifestyle. But a meta-analysis of several obesity studies found that six new obesity genes are expressed in the brain.
Scientists from the international GIANT (Genetic Investigation of Anthropometric Parameters) consortium analyzed data from 15 genome-wide association studies and identified six new candidate genes that were related to regulation of body weight. Several of these new genes are highly expressed or known to act in the brain, emphasizing the role of the central nervous system in predisposition to obesity.
