SLC34A3 is almost exclusively expressed at the apical membranes of kidney proximal tubules and encodes a Na+/Pi cotransporter. It cotransports 2 Na+ ions with every phosphate (Pi) (electroneutral transport). Defects in SLC34A3 are the cause of hereditary hypophosphatemic rickets with hypercalciuria (HHRH; MIM:241530), an autosomal recessive form of hypophosphatemia characterised by reduced renal phosphate reabsorption and rickets (Bergwitz et al. 2006, Segawa et al. 2013, Forster et al. 2013).
