CETP gene haplotypes raise cardiovascular risk partly through mechanisms independent of triglycerides and HDL cholesterol (Int J Mol Sci 2023)
Original title: Association of CETP Gene Polymorphisms and Haplotypes with Cardiovascular Risk
This study investigated the effect of five CETP gene single-nucleotide polymorphisms and their haplotypes on 10-year cardiovascular risk (CVR), estimated by the SCORE, Framingham coronary heart disease, and Framingham cardiovascular disease algorithms, in 368 samples from the Hungarian general and Roma populations. The T allele of rs7499892 showed a significant association with increased CVR by the Framingham score, and haplotypes H5, H7, and H8 each showed significant association with increased CVR by at least one algorithm. The effect of H5 was explained by its impact on triglyceride and HDL-cholesterol levels, while H7 and H8 showed significant associations with cardiovascular risk mediated by mechanisms affecting neither triglycerides nor HDL-cholesterol. The authors conclude that CETP gene polymorphisms affect cardiovascular risk partly through presently unknown mechanisms beyond their known lipid effects.
Original abstract
Cholesteryl ester transfer protein (CETP) is known to influence HDL-C levels, potentially altering the profile of HDL subfractions and consequently cardiovascular risk (CVR). This study aimed to investigate the effect of five single-nucleotide polymorphisms (SNPs; rs1532624, rs5882, rs708272, rs7499892, and rs9989419) and their haplotypes (H) in the CETP gene on 10-year CVR estimated by the Systematic Coronary Risk Evaluation (SCORE), the Framingham Risk Score for Coronary Heart Disease (FRSCHD) and Cardiovascular Disease (FRSCVD) algorithms. Adjusted linear and logistic regression analyses were used to investigate the association of SNPs and 10 haplotypes (H1-H10) on 368 samples from the Hungarian general and Roma populations. The T allele of rs7499892 showed a significant association with increased CVR estimated by FRS. H5, H7, and H8 showed a significant association with increased CVR based on at least one of the algorithms. The impact of H5 was due to its effect on TG and HDL-C levels, while H7 showed a significant association with FRSCHD and H8 with FRSCVD mediated by a mechanism affecting neither TG nor HDL-C levels. Our results suggest that polymorphisms in the CETP gene may have a significant effect on CVR and that this is not mediated exclusively by their effect on TG and HDL-C levels but also by presently unknown mechanisms.
