Genetic susceptibility of five tagSNPs in the endothelin-1 () gene to coronary artery disease in a Chinese Han population.

Endothelin-1 (ET-1) plays important roles in endothelial dysfunction, vascular physiology, inflammation, and atherosclerosis. Nonetheless, the role of ET-1 () gene variants on coronary artery disease (CAD) risk remains poorly understood. The aim of the present study was to evaluate the role of gene polymorphisms on individual susceptibility to CAD.
