ABCG2 SNPs rs2231142 (Q141K) and rs10011796 and, for comparison, the SLC2A9 SNP rs11942223 were tested for allelic association with (a) gout in the presence of HU (Table 1; gout vs. HU), (b) gout per se (Table 1; gout vs. all controls), (c) HU (Table 1; HU vs. NU) and, (d) serum urate levels in controls (Table 2). Here, ABCG2 is linked to gout.
