ABCG2 and gout: Previous genetic studies have revealed that gout has associations with various genes such as ATP-binding cassette transporter, subfamily G, member 2 (ABCG2/BCRP) [1–4], monocarboxylate transporter 9 (MCT9/SLC16A9) [5], organic anion transporter 4 (OAT4/SLC22A11) [6], leucine-rich repeat-containing 16 A (LRRC16A/CARMIL) [7], and alpha-protein kinase 1 (ALPK1) [8].
