I405V and -629C/A polymorphisms of the cholesteryl ester transfer protein gene in patients with coronary artery disease.
Cholesteryl ester transfer protein (CETP) plays a main role in high-density lipoprotein metabolism. CETP gene possesses several single nucleotide polymorphisms which have been associated with plasma high-density lipoprotein cholesterol (HDL-C) concentrations. The aim of this study was to determine the association of CETP -629C/A and I405V polymorphisms with coronary artery disease (CAD) in Iranian population.



The presence of two CETP gene polymorphisms -629C/A and I405V were studied in 187 unrelated CAD cases and 136 controls. All the samples were clinically examined and lipid profile was estimated. Genotyping was performed using polymerase chain reaction/restriction fragment length polymorphism method.



The frequency of -629C/A and I405V allelic variants were found to be 0.732 and 0.366 in cases and 0.658 and 0.348 in controls, respectively. The frequency of A allele of -629C/A polymorphism in cases was significantly higher than that of controls. HDL-C in AA genotype was higher than CA and CC genotypes in controls. No significant effect of II, IV and VV genotypes was found in lipid profiles.



No significant association was found between CETP I405V polymorphism and increased risk of CAD in Azeri population studied. AA genotype of -629C/A increased HDL but the risk of CAD in this genotype might be higher than CC genotype.
