Coronary artery disease (CAD) is a significant contributor to global health burden. Adiponectin gene single nucleotide polymorphisms (SNPs) have been associated with CAD susceptibility, but with inconsistent results across the studies. We present, in this study, an updated meta-analysis to discern the genetic susceptibility of adiponectin SNPs in relation to CAD. PubMed and EMBASE databases were used to identify the relevant published articles using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Pooled odds ratios and 95% confidence intervals were generated to assess the strength of the associations. Thirty-five articles with a total of 28,947 participants (mean age 55.3 years, 11,632 cases/17,315 controls, 19,443 males/8353 females, and 1151 persons with unspecified gender data) were included. The dominant, recessive, and additive models were applied. We found that the SNPs +45T>G (rs2241766), −4034A>C (rs822395), and −11391G>A (rs17300539) were linked to CAD development. In addition, +276G>T (rs1501299) SNP was associated with a decreased susceptibility to CAD among Caucasians. We did not find an association between the CAD susceptibility and the −11377C>G (rs266729) SNP. These observations offer new potential genetic biomarker candidates in relation to CAD, and warrant further research in independent world populations.
