The human SLC2A9 gene encodes the class II facilitative glucose transporter 9 (GLUT9). SLC2A9 is expressed mainly in kidney (proximal tubules of epithelial cells) and liver. SLC2A9 mediates the transport of urate (uric acid), the end product of purine metabolism in humans and great apes. In addition it mediates the uptake of fructose (Fru) and glucose (Glc) at a low rate. Defects in SLC2A9 can cause renal hypouricemia 2 (RHUC2), a common inherited disorder characterised by impaired renal urate reabsorption and resultant low serum urate levels. Some patients present with severe complications, such as exercise-induced acute kidney injury (EIAKI) and nephrolithiasis. Mutations in SLC2A9 that cause RHUC2 include R380W, R198C, L75R, R171C, T125M, G216R and W23* (Matsuo et al. 2008, Dinour et al. 2010, Dinour et al. 2012, Stiburkova et al. 2012, Shen et al. 2014).
