Recent GWASs of clinically defined gout have revealed associations between gout and urate transporter genes, such as ABCG2/BCRP, URAT1/SLC22A12, GLUT9/SLC2A9, NPT1/SLC17A1 [16–19], all of which are expressed in the proximal tubular cells of the kidney [17]. The gene discussed is ABCG2; the disease is gout.
