Gene variant found to increase risk of cardiomyopathy seven-fold in South Asians 1

A paper in Nature Genetics reports a seven-fold increase in cardiomyopathy in South Asians with a common 25 base pair deletion of the cardiac myosin binding protein C (MYBPC3). The variant occurs more frequently in southern and western India than in the north, and this distribution correlates with higher rates of heart failure in southern India, according to a press release from Nature.
