There are studies on these which report an association between CDC42BPG and hyperuricaemia from the Japanese exome-wide association study,29 and GWAS on SUA from a Korean population.30 The significance around rs11231879 of CDC42BPG was, however, no longer evident when conditioned on rs11231879 itself, nor when conditioned on the secondarily significant SNP, rs56093838 of SLC22A12/URAT1, demonstrating that these signals were from the same locus (see online supplementary figure S2). This evidence concerns the gene SLC22A12 and hyperuricemia.
