ObjectiveTo evaluate the association between the Single Nucleotide Polymorphism (SNP) BsmI (rs1544410) in the vitamin D receptor gene and the susceptibility of coronary artery disease. MethodsDatabases including PubMed, Web of Science, CNKI, WanFang Data, VIP and CBM were searched from inception to May, 2016 to collect case-control studies about SNP BsmI (rs1544410) in the vitamin D receptor gene and the susceptibility of coronary artery disease. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Then Meta-analysis was performed by using RevMan 5.3. ResultsA total of seven studies were included, which involved 2182 patients and 5925 controls. The results of meta-analyses showed that the B allele and BB genotype in rs1544410 was associated with the risk of coronary artery disease (B vs. b:OR=1.36, 95%CI 1.03 to 1.79, P=0.03; BB vs. bb:OR=1.70, 95%CI 1.06 to 2.72, P=0.03; BB+Bb vs. bb:OR=1.52, 95%CI 1.00 to 2.30, P=0.05). Subgroup analysis by age showed that rs1544410 was associated with the risk of coronary artery disease in the age <65(B vs. b:OR=1.65, 95%CI 1.00 to 2.73, P=0.05; BB vs. Bb+ bb:OR=1.79, 95%CI 1.08 to 2.97, P=0.02; BB vs. bb:OR=2.64, 95%CI 1.12 to 6.25, P=0.03). Subgroup analysis by ethnicity showed that rs1544410 was associated with the risk of coronary artery disease in Caucasians (B vs. b:OR=1.47, 95%CI 1.10 to 1.97, P=0.01; BB+Bb vs. bb:OR=1.71, 95%CI 1.09 to 2.68, P=0.02; BB vs. Bb+bb:OR=1.39, 95%CI 1.01 to 1.92, P=0.05; BB vs. bb:OR=1.80, 95%CI 1.10 to 2.95, P=0.03). Subgroup analysis by genotyping methods showed that rs1544410 was associated with the risk of coronary artery disease in the TaqMan (B vs. b:OR=2.18, 95%CI 1.06 to 4.45, P=0.03; BB+Bb vs. bb:OR=3.32, 95%CI 1.06 to 10.40, P=0.04; BB vs. bb:OR=3.31, 95%CI 1.06 to 10.30, P=0.04). Subgroup analysis by diagnostic criteria for cases showed that rs1544410 was associated with the risk of coronary artery disease in the ECG (B vs. b:OR=1.15, 95%CI 1.02 to 1.29, P=0.02; BB+Bb vs. bb:OR=1.22, 95%CI 1.02 to 1.45, P=0.03; BB vs. bb:OR=1.31, 95%CI 1.03 to1.67, P=0.03). ConclusionBsmI (rs1544410) B allele may have a significant association with the high risk of coronary artery disease especially the Caucasians and the ones with age <65.
