SLC2A9 and hypouricemia, renal: Exercise-induced acute kidney injury (EIAKI), a hereditary pathological condition frequently developed in patients with renal hypouricemia (RHUC), due to increased renal urate clearance as a result of genetic mutations in the urate transporter URAT1 (RHUC1) or GLUT9 (RHUC2) (32) that reabsorbs urate in the renal proximal tubule.
