Significant interaction of APOE rs4420638 polymorphism with HDL-C and APOA-I levels in coronary heart disease in Han Chinese men
Apolipoprotein E (APOE) is recognized for its importance in lipoprotein metabolism and cardiovascular disease. We evaluated the association between APOE rs4420638 genotypes and circulating lipid concentrations along with the risk of coronary heart disease (CHD). We conducted a case-control study involving 1508 individuals to investigate the contribution of rs4420638 to the risk of CHD in Han Chinese. In addition, we performed a meta-analysis to evaluate the association between rs4420638 and CHD in Europeans and Asians.
