Abstract:
Objective To detect the distribution of SLC2A9 rs10489070 polymorphism genotypes in Chinese Han population,and to explore the association of this gene polymorphism with gout susceptibility,tophi,serum uric acid levels and other clinical and laboratory data.Methods A total of 151 primary gout patients and 176.healthy controls were enrolled into this study.The genotypes and alleles frequencies were calculated by using TaqMan(R) SNP Genotyping Assays and the possible association between gene polymorphism of SLC2A9 and gout was investigated.T test,Chi-square and Fisher exact probabilities were used for statistcal analysis.Results Genotypes distribution were in Hardy-Weinberg equilibrium in gout patients and controls (P＞0.05).The frequency of CC genotype in gout patients was significantly higher than that in the controls (78.8％ vs 68.5％,P＜0.05),aand the frequency of CG genotype in gout patients was significantly lower (19.9％ vs 30.1％,P＜0.05).However,there were no statistical differences in the alleles frequencies of C and G between gout patients and controls (P＞0.05).Interestingly,there was significant difference in the distribution of genotypes between tophaceous gout patients and non-tophaceous gout patients (P＜0.05),and the frequency of CG genolype was much lower in tophaceous gout patients (0 vs 22.7％,P＜0.05).Conclusion Results of present study suggest that rs10489070 polymorphism of the SLC2A9 gene might be associated with gout development.CC genotype predisposes to gout,and CG genotype might protect Chinese Han population from gout and tophi development.
