Genetic variants of the endothelial NO synthase gene (eNOS) may confer increased risk of sporadic congenital heart disease
The endothelial NO synthase (eNOS) enzyme is expressed during the early stages of cardiogenesis and plays an important role in normal heart development. Genetic variations of eNOS G894T have been shown to influence individual susceptibility to some phenotypes of congenital heart disease (CHD) in different populations. We conducted a case-control study comprised of 945 CHD patients and 972 non-CHD individuals in a Chinese population.
