SLC2A9 and gout: Our present study showed a high degree of association between gout and SNPs in ABCG2 and SLC2A9, those polymorphisms that were reported to have highest effects on serum UA levels found in the previous meta-analysis (explaining 0.57% and 3.53% of variability, respectively) [7] and that showed ORs for gout between 1.37 and 1.52 in our study.
