Abstract :
To better understand the role of cholesteryl ester transfer protein (CETP) in cardiovascular disease, nine polymorphisms spanning the gene from the upstream promoter region to beyond the 3′UTR were genotyped in 2553 individuals from multiple ethnic groups and with different cardiovascular disease profiles. The frequency of four of these SNPs varied by 40–300% between Caucasians and African Americans. SNPs in each ethnic group fell into two haploblocks with significant linkage disequilibrium within each block. SNPs in the 5′ haploblock were significantly associated with HDL cholesterol while SNPs in the 3′ haploblock were, at best, only weakly associated with HDL-C. One SNP in the 3′ haploblock (rs1800774 in intron 12) was highly associated with history of myocardial infarction even though it was not associated with HDL-C. This association was driven by the effect in Caucasian women where 11.9% of the women with no history of MI are homozygous for the less common allele while 23.7% of those with a history of MI share this genotype. In addition, this SNP was highly associated with BMI among Caucasians (p < 0.0001). The association of HDL-C with CETP genotype was found to be independent of smoking or alcohol consumption. These results replicate some earlier findings and also help to explain some of the apparent contradictions in the literature surrounding the role of CETP in modulating HDL-C and cardiovascular disease.
