Popis: BACKGROUND: Colesteryl ester transfer protein (CETP) plays a key role in the metabolism of lipoproteins; therefore, polymorphisms of its gene can affect susceptibility to coronary artery disease (CAD) in diabetes mellitus. The aim of the present study was to investigate association between I405V polymorphism of CETP gene and risk of CAD in patients with type 2 diabetes mellitus. METHODS: The current case-control study was conducted on 143 patients with type 2 diabetes and angiographically diagnosed CAD and 150 patients with type 2 diabetes and without CAD. Genotyping was performed through polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. The presence of CAD was defined as higher than 50% reduction in coronary artery diameter. RESULTS: The genotype frequencies of I405V polymorphism were II (27.3% vs. 23.2%), IV (61.5% vs. 67.5%), and VV (11.2% vs. 9.3%) in diabetic with CAD compared to diabetic without CAD (χ2 = 1.164) (P = 0.55). The I and V alleles were found at frequencies of 63.6% and 61.6% in the diabetic with CAD group and 36.4% and 38.4% in the diabetic without CAD group (χ2 = 0.263) (P = 0.60). No significant difference was observed between two groups in terms of genotype and allele frequency. Moreover, no significant association was observed between II, IV, and VV genotypes and lipid profiles in both groups. However, a significant difference was observed between genotype distributions of I405V polymorphism in men according to the severity of CAD. CONCLUSION: It is speculated that I405V polymorphism may be associated with the severity of coronary artery stenosis only in men with type 2 diabetes mellitus.
