Endothelial nitric oxide synthase and angiotensinogen gene polymorphism in coronary artery diseases in Egypt.
Genetic factors contribute to the pathogenesis of coronary artery disease (CAD). We studied 100 patients with CAD and 50 healthy individuals to assess the association of endothelial nitric oxide (eNOS) polymorphism (Glu298Asp) and angiotensinogen polymorphisms (M235T) and CAD in an Egyptian population. Serum nitric oxide (NO) and angiotensin I levels were also measured. The frequency of Glu298Asp and M235T polymorphisms were higher in the CAD group compared with controls. The mean level of NO was significantly lower (P < .05) while angiotensin I was significantly higher (P < .05) in patients CAD than in controls. The frequency of eNOS TT allele of M235T variant was significantly higher in patients with CAD (20% vs 6%). The frequency of angiotensinogen (AGT) TT and T allele in patients with CAD was significantly higher (P < .05) than in controls (22% vs 6%and 47% vs23%, respectively). Homozygosity for Glu298Asp and M235T polymorphisms may predispose to CAD.
