The cholesteryl ester transfer protein (CETP) is a plasma glycoprotein that transfers neutral lipids between plasma lipoproteins. The distributions of variations in the CETP gene and their influences on lipid levels were investigated among random members of the Koren population (n=270) whose profiles of environmental factors were known. The frequencies of the major allele at BamHI, EcoNI, TaqIA, TaqIB, New HinfI RFLPs, and the D442G mutation were 0.77, 0.55, 0.84, 0.62, 0.81, and 0.94, in serial order. The significant associations of the GamHI RFLP and the D442G mutation with the plasma high density lipoprotein(HDL) cholesterol levels were observed in this population. Subjects with geno type B2B2 of the BamHI RFLP had significantly lower HDL cholesterol levels than the mean of total subjects. Subjects with D442G mutant allele had a significantly higher HDL cholesterol levels only in makes. Analysis of the covariance model(ANOCOVA) showed that allelic variations in the BamHI RFLP and the D442G mutation sites accounted independently fot 4.0 and 5.9% of the total inter-individual variation in plasma HDL cholesterol in males (F=2.29, p=0.10; F=3.4, p=0.03). The effect of the CEPT genotype was very high (about 10%), compared to the total effects of sex, body mass index, age, and smoking habit (20%). In conclusion, the genetic variation of the CETP gene is related to the regulation of plasma HDL cholesterol levels and the extent of the effect seems to be different between make and female in the Korean population.
