In this study, we analyzed single nucleotide polymorphisms (SNP) in urate transporter genes to examine the pathogenesis of gout. We conducted a 1:1-matched case-control study that included 110 patients with acute gout attacks as the patient group and 110 healthy age- and gender-matched subjects as the control group. Clinical parameters were recorded and blood biochemistry tests were conducted for both groups. Multivariate logistic regression analysis was used to analyze the data. Hyperuricemia, hypercholesterolemia, and hypertriglyceridemia were found to be the main risk factors for the onset of gout, with relative risks of 29.2 (P 0.05). The risk factors of gout were hyperuricemia, hypercholesterolemia, hypertriglyceridemia, and the T/T genotype of the rs2231142 locus in the ABCG2 gene; expression of the G/G genotype may be a protective factor against gout development.
