Association of E-Selectin gene polymorphisms and serum E-Selectin level with risk of coronary artery disease in lur population of Iran

Abstract

Background: Adhesion molecules like E-selectin have important role in pathogenesis of atherosclerosis. C1901T and G98T polymorphisms of E-selectin gene and E-selectin serum level may affect the risk of coronary artery disease (CAD). Methods: A total of 145 normal individuals and 154 patients diagnosed with CAD from the Lur population of Iran undergoing coronary angiography were enrolled. Genetic polymorphisms of E-selectin were determined using PCR-RFLP. Serum level of soluble E-selectin was measured using Elisa. Results: T allele in C1901T polymorphism was significantly associated with an increased risk of atherosclerosis (P = 0.018). No significant association was observed for G98T polymorphism. The mean serum level of soluble E-selectin in the patient group was significantly higher than the control group (P < 0.001). Conclusions: Allele type in C1901T polymorphism plays a role in increasing the risk of developing CAD. Furthermore, since serum E-selectin level is associated with systemic inflammation, it contributes to the increased risk of the disease.
