Experimental studies and genome-wide association studies (GWAS) have identified a number of genes and their protein products that serve as UA transporters in the kidney: SLC22A12 [UA transporter (URAT1)], SLC2A9 (GLUT9), ABCG2 [ATP-binding cassette subfamily 2 also known as breast cancer resistance protein (BCRP)], SLC22A6 [organic anion transporter (OAT1)], SLC22A7 (OAT2), SLC22A8 (OAT3), SLC22A11 (OAT4), SLC22A13 (OAT10), SLC17A1 [Na + /phosphate transporter (NPT1)], SLC17A3 (NPT4), ABCC4 [multidrug resistance protein 4 (MRP4)] and PDZK1 (PZK domain containing 1 protein)
