FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a renal thiazide-sensitive sodium-chloride cotransporter that is important for electrolyte homeostasis. This cotransporter mediates sodium and chloride reabsorption in the distal convoluted tubule. Mutations in this gene cause Gitelman syndrome, a disease similar to Bartter's syndrome, that is characterized by hypokalemic alkalosis combined with hypomagnesemia, low urinary calcium, and increased renin activity associated with normal blood pressure. This cotransporter is the target for thiazide diuretics that are used for treating high blood pressure. Multiple transcript variants encoding different isoforms have been found for this gene.

PHENOTYPE: Mice homozygous for a knock-out allele exhibit hypomagnesemia, hypocalciurua and abnormal renal distal convoluted tubule morphology, and show significantly reduced arterial blood pressure on a sodium-depleted diet. Mutant kidney cortical collecting ductsdisplay thiazide-sensitive NaCl absorption. [provided by MGI curators]
