A gene is identified through the study of Iceland’s comprehensive records, which is supposed to be responsible for the predisposition of type 2 diabetes. According to the study researchers, a single genetic change (in this identified gene variant TCF7L2)) could predispose almost 40% of the population to type 2 diabetes.
Type 2 diabetes is a serious worldwide health problem. It affects nearly 200 million people worldwide and 18 million people in the United States alone. This study can help a lot in the development of an easy test for diabetes risk and might also lead to better drugs for the disease.
According to the study researchers the people having one variant of this identified gene have 40% more chances of getting type 2 diabetes. Whereas in the people who have 2 variants of this gene, the risk of getting diabetes is increased up to 140%. However, if this gene is detached from the population almost 20% of the type 2 diabetes cases can be removed from the society.
The researchers believe that this discovery sheds a new light on the biological causes of the disease. It can also be an exciting starting point for the discovery of new drugs and we can aggressively pursue the development of both diagnostic and therapeutic products to prevent and treat type 2 diabetes.
