SLC34A3 mutations in patients with hereditary hypophosphatemic rickets with hypercalciuria predict a key role for the sodium-phosphate cotransporter NaPi-IIc in maintaining phosphate homeostasis. Am J Hum Genet. 2006;78:179-92 pubmed
    ..We conclude that NaP(i)-IIc has a key role in the regulation of phosphate homeostasis. ..
