Abstract

Background and Aims It has been reported that rs1122608 adjacent to low-density lipoprotein cholesterol receptor (LDLR) locus is associated with the risk of coronary artery disease (CAD) and blood lipid profile in the Caucasian population. Due to the contradictory results in the Asian population, we conducted a meta-analysis to systematically summarize and clarify the association between rs1122608 with CAD risk and lipid profile. Methods A systematic search regarding studies on the association of rs1122608 with CAD risk and lipid profile was conducted in databases including PubMed, Embase, and Cochrane library. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were used to pool the effect size. Results A total of five case-control studies were included in this study. A statistically significant association was identified between rs1122608-G allele and CAD risk in overall analysis (OR = 2.09, 95% CI 1.48–2.97) and in both Asian (OR = 1.82, 95% CI 1.04–3.18) and Caucasian subgroups (OR = 2.31, 95% CI 1.48–3.60). The rs1122608-G allele was associated with increased triglyceride (TG) level (OR = 1.25, 95% CI 1.03–1.52), but not with total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), or LDL cholesterol level. Moreover, the rs1122608-G allele is associated with increased CAD risk in the Asian male population (OR = 3.37, 95% CI 1.51–9.86) but not in the Asian female population. Conclusions The rs1122608 is associated with the risk of CAD and TG level. The rs1122608-G allele was a significant risk factor of CAD in the Asian male population but not in the Asian female population.
