Of these, the loci of ABCG2 and SLC2A9 were also detected in the previous GWAS of gout cases and normouricaemia controls.24 rs671 of ALDH2 was identified as a gout-associated SNP in a subsequent fine mapping study.46 The present study therefore identified rs671 of ALDH2 as a gout locus by GWAS for the first time. This evidence concerns the gene SLC2A9 and gout.
