Abstract

Abstract We investigated the interactions ofALPK1 variants and the loci ofABCG2, SLC2A9, andSLC22A12 on gout risk. We conducted two case–control studies. Participants were recruited from hospitals (n = 410; 104 gout cases and 306 controls) and communities (n = 678; 373 gout cases and 305 controls) in Taiwan. The genotypes ofALPK1 (rs11726117 M861T, rs231247 R1084R, and rs231253 3′ UTR), ABCG2 (rs2231142 Q141K and rs2231137 V12M), SLC2A9 (rs3733591 R265H and rs1014290), andSLC22A12 (rs3825016 H86H, rs11231825 H142H, and rs475688) were genotyped. Under a recessive model, the joint effects ofALPK1 variants and the SNPs rs2231142 ofABCG2, rs1014290 ofSLC2A9, or rs475688 and rs3825016 ofSLC22A12 were associated with gout. The rs11726117 [CC] ofALPK1 and rs2231142 [TT] ofABCG2 with the sequential addition of the rs1014290 [AA] ofSLC2A9 and rs3825016 [CC] ofSLC22A12 were associated with gout risk (odds ratio (OR): 13.01, 15.11, and 55.00 and positive predictive value (PPV): 56%, 69%, and 99% in the Han group, respectively; OR: 3.76, 5.78, and 12.30 and PPV: 74%, 80%, and 81% in the aboriginal group, respectively). Combined exposure to the four high-risk genotypes ofALPK1 and the uric-acid-related loci ofABCG2, SLC2A9, andSLC22A12 was associated with an increased gout risk and a high PPV for gout.
