Atrial fibrillation (AF) is the most common arrhythmia with multi-factorial pathogenesis. A number of studies of genetic epidemiology have assessed the association of G112A (G38S) single nucleotide polymorphisms (SNPs) in Mink gene with AF in different populations. However, the results are inconsistent and inconclusive. We performed a Meta-analysis of the association between G112A polymorphisms of MinK gene and AF to estimate the magnitude of the gene effect. Six case-control studies with a combined 854 cases and 1079 controls were summarized. Subgroups in different races were separately analyzed. Heterogeneity and publication bias were also explored. When all groups were pooled, the individuals with G allele had an over 40% higher risk of AF compared with individuals with the A allele. The GG genotype (versus AA genotype) was found to be significant association with increased AF risk. The significant associations were also found in both dominant and recessive genetic model. For subgroup analysis, the results were consistent with above, except that the pooled OR for Chinese population was not significant in a recessive genetic model. In conclusion, G112A polymorphisms in Mink gene may have an important effect on the pathogenesis of AF. This warrants further investigation in large multi-center studies with precise design. 展开更多
