Description

 Solute carrier family 4 (sodium bicarbonate cotransporter), member 4 (HGNC Symbol)

Entrez gene summary

 This gene encodes a sodium bicarbonate cotransporter (NBC) involved in the regulation of bicarbonate secretion and absorption and intracellular pH. Mutations in this gene are associated with proximal renal tubular acidosis. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2008]
