Coronary atherosclerosis, the most common form of coronary artery disease (CAD), is characterized by accumulation of lipid in the walls of coronary arteries. Recent data from clinical trials have showed that high-density lipoprotein cholesterol (HDL-C) has causal role in the pathogenesis and development of coronary atherosclerosis. Cholesteryl ester transfer protein (CETP) is an important regulator of plasma HDL-C. Several genetic mutations in the CETP gene were found to be associated with HDL-C levels. The aim of the present study is to evaluate the association of HDL-C-related CETP polymorphisms and risk of coronary atherosclerosis.


We investigated the association of seven single nucleotide polymorphisms (SNP) (rs1800775, rs708272, rs5882, rs1532624, rs1864163, rs7499892, and rs9989419) in the CETP gene with the risk of coronary atherosclerosis and levels of HDL-C in a case-control study in China. Included in the study were 420 patients with coronary atherosclerosis and 424 healthy controls. SNP genotyping was performed by TaqMan allelic discrimination assay and serum lipid levels were measured by standard laboratory methods.


Carriers of the AA and GA + AA genotypes of rs708272 had significant lower risks of coronary atherosclerosis (OR = 0.55, 95% CI: 0.36-0.85, p = 0.003; OR = 0.67, 95% CI: 0.50-0.90, p = 0.007, respectively) compared to those with GG genotype. These relations remained significant after adjustment for confounding effects of age, smoking, diabetes and hypertension. The rs1800775 polymorphism was significantly associated with serum levels of HDL-C in healthy controls (p = 0.04). Besides, rs708272 was in close linkage disequilibrium (LD) with rs1800775 in this study.


Our findings indicated that CETP rs708272 may be associated with the risk of coronary atherosclerosis and rs1800775 may influence serum HDL-C levels in healthy controls in Chinese.
