Cholesterol ester transfer protein, apolipoprotein E and lipoprotein lipase genotypes in patients with coronary artery disease in the Turkish population

The aim of this study was to compare patients with coronary artery disease (CAD) to healthy objects, in order to explore a possible association between CAD and the variants in the gene encoding cholesterol ester transfer protein (CETP), apolipoprotein E (Apo E) and lipoprotein lipase (LPL). The relationship between CETP MspI, apo E and LPL PvuII gene polymorphisms and serum lipids were investigated in 173 patients with CAD and 111 healthy controls. The frequency of Apo epsilon4 (p<0.05) and CETP M1 (p<0.01) alleles were higher in the CAD group than in the control group. In the CAD group, those with the Msp M1 allele had higher levels of total cholesterol (TC) (p=0026) and low-density lipoprotein cholesterol (LDL-C) than those with the Msp M2 allele. Subjects with an epsilon2 allele had the lowest levels of TC and LDL-C, while subjects with the epsilon4 allele had the highest. In the control group, CETP, the Msp M2 allele was associated with a higher level of high-density lipoprotein cholesterol (HDL-C) (p=0.012) than the Msp M1 allele. The distributions of LPL genotype and allele did not differ between the CAD and control groups. The present study demonstrates that the CETP Msp1 and Apo E gene polymorphisms are associated with variations in lipids in patients with CAD and healthy controls in Turkish population.
