Cholesteryl ester transfer protein Taq1B polymorphism in an angiographically assessed Turkish population: no effects on coronary artery disease risk.

BACKGROUND
Taq1B polymorphism of cholesteryl ester transfer protein (CETP) is believed to associate with high-density lipoprotein-cholesterol (HDL-C) levels and may alter the susceptibility to atherosclerosis.


AIM OF THE STUDY
This study investigated the effects of Taq1B polymorphism on HDL-C and coronary artery disease (CAD) risk in angiographically defined CAD patients.


METHODS
One hundred thirty-five CAD patients and 112 healthy controls were screened for the CETP Taq1B genotype and plasma lipids.


RESULTS
The genotype frequency of CAD patients and controls were similar. The HDL-C levels of all genotypes in the CAD group were significantly lower than the corresponding controls. Smoking and plasma triglycerides were the predictors of the HDL-C level in B1B1 bearers, whereas the subjects with a polymorphic B2 allele were affected by smoking and sex.


CONCLUSION
CETP Taq1B polymorphism neither plays a role in determining HDL-C levels nor is a useful predictor of the risk of CAD.
