SLC2A9 and gout: Several recent genome-wide association studies (GWAS) and follow-up studies identified that genetic variants of SLC2A9 had a role in affecting urate concentrations [10], [11], [16], [17], [18], [19], [20], [21], [22], [23], [24] and susceptibility to gout [10], [16], [25], [26], [27], [28], [29], [30].
