ABSTRACT
To investigate the association between family history of cardiovascular disease [CVD] and cholesteryl ester transfer protein [CETP] TaqIB polymorphism in Taiwanese subjects. In this cross-sectional study, 240 subjects [115 men and 125 women] were divided into two groups based on whether or not they had a parental history of CVD. Polymerase chain reaction/restriction fragment length polymorphism was used to analyze the genotype of the subjects for the TaqIB polymorphism of CETP in intron 1. The frequency of the B1B1 genotype was significantly higher in Taiwanese subjects with a family history of CVD than in those without it [31.2 vs. 18.8%, odds ratio = 1.97, 95% confidence interval = 1.084-3.579, p = 0.035]. Siblings with the B1B1 genotype had lower levels of serum high-density lipoprotein cholesterol [HDL-C] than siblings with either B1B2 [46.7 +/- 11.0 vs. 52.5 +/- 11.1 mg/dl, p = 0.034] or B2B2 genotypes [46.7 +/- 11.0 vs. 55.2 +/- 9.6 mg/dl, p = 0.01]. CETP TaqIB polymorphism is associated with plasma HDL-C levels. The CETP B1B1 genotype may influence the susceptibility to CVD in Taiwan
