An HphI polymorphism in the E-selectin gene is associated with premature coronary artery disease.

An increased expression of E-selectin has been observed in the arterial endothelium interacting with lymphocytes and macrophages in human atherosclerotic lesions. We examined whether a polymorphism in the E-selectin gene, due to a G to T mutation (G98T) in the untranslated region of exon 2, was associated with premature coronary artery disease (CAD). Other lipid and nonlipid risk factors including a Ser to Arg (S128R) substitution in the E-selectin gene were also assessed. In patients with premature CAD (men < or = 45 years old and women < or =55 years old, N = 51) who underwent an elective diagnostic coronary arteriography, the frequency of the mutation was significantly higher than in controls (N = 50, 0.22 vs. 0.10, p = 0.024). After controlling for other CAD risk factors (plasma total cholesterol, triglyceride, LDL-apolipoprotein B. cigarette smoking and the S128R mutation) by multiple logistic analysis, the G98T mutation in the E-selectin gene was still a significant predictor of premature CAD [p = 0.022, odds ratio (95%, CI)= 3.58 (1.20-10.67)].
