Previous function-based genetic studies [1–3] and genome-wide association studies (GWASs) [4–6] have revealed that gout is associated with several genes, such as ATP-binding cassette transporter, subfamily G, member 2 (ABCG2/BCRP) and glucose transporter 9 (GLUT9/SLC2A9). The gene discussed is SLC2A9; the disease is gout.
