Background and Objectives：Cholesteryl ester transfer protein (CETP) plays a key role in the reverse cholesterol transport pathway. The purpose of this study was to investigate the association of CETP gene polymorphism with the plasma lipid levels and coronary artery disease (CAD) in Korean men.
Subjects and Methods：Two hundred and sixteen healthy control subjects (46.8±10.6 y) and 95 patients with CAD (58.2±8.8 y) were examined. The genotypes of C-629A, Taq1B and I405V were determined by the SNP-IT assay.
Results：The allele frequencies of the C：A in the C-629A, B1：B2 in the Taq1B and I：V in the I405V in the control group were 0.51：0.49, 0.63：0.37 and 0.55：0.45, respectively. The genotype distributions of the C-629 A and Taq1B polymorphisms in the CAD patients did not differ from those in the control group. No variation in the CETP genotype was associated with disease progression in the CAD group. The HDL cholesterol in -629A homozygous and Taq1B B2 homozygous were higher than those of the other genotypes. The Taq1B B2 carrier was an independent determinant for HDL cholesterol in the control group. However, I405V polymorphism was not associated with HDL cholesterol. The V allele in the I405V polymorphism was associated with reduced CAD events after controlling the age, BMI and other risk factors (OR：0.4, p<0.01).
Conclusion：The frequencies of Taq1B and C-629A variants between the healthy and CAD groups did not differ. The B2 carrier in the Taq1B polymorphism was associated with a higher HDL cholesterol concentration. The V variation in the I405V polymorphism had a protective effect against the development of CAD in Korean men.
