The relationship between the SLC2A9 (solute carrier family 2, member 9) gene polymorphisms and gout was still inconsistent among the individual genetic association studies. Therefore, this present research was aimed to systematically evaluate the association between SLC2A9 gene polymorphisms and gout susceptibility. Relevant studies were enrolled by searching databases systematically. The pooled odds ratios (ORs) with 95 % confidence intervals (CIs) were used to assess the associations. The heterogeneity between each of the studies was calculated by using the Q statistic methods, and Begg's funnel plot and Egger's tests were performed to evaluate publication bias. A total of 13 studies investigated four single nucleotide polymorphisms (SNPs) in SLC2A9 were included. In this study, we found that the allele C of rs3733591 was higher in patients than in controls in both all-pooled population [C vs. T: OR (95 % CI) = 1.432 (1.213-1.691)] and Asians-pooled population [C vs. T: OR (95 % CI) = 1.583 (1.365-1.835)]. The allele frequency C of s6449213 was lower in the gout patients than in controls in both all-pooled population and Caucasians-pooled population. Additionally, the allele frequency T of rs16890979 and the allele frequency C of rs1014290 were lower in gout patients than in controls. This study demonstrated that the genetic susceptibility for gout is associated with the SLC2A9 gene polymorphisms. Four of them except for the rs3733591 are protective SNPs in Caucasians, and rs16890979 and rs1014290 are protective SNPs in both Caucasians and Asians, while rs3733591 may be susceptibility SNP in Asians.
