Although inhibition of any of these transporters would cause uricosuria, we postulate that GLUT9 inhibition is particularly influential in the effect of tranilast, given the more severe uricosuric phenotype for patients with GLUT9‐deficient, versus URAT1‐deficient, renal hypouricemia (Dinour et al. This evidence concerns the gene SLC2A9 and hypouricemia, renal.
