Short name: Barttin

Overlapping homologous superfamilies


Family relationships



Barttin is a beta-subunit for ClC-Ka and ClC-Kb chloride channels, with which it co-localises in basolateral membranes of renal tubules and of potassium-secreting epithelia of the inner ear [PMID: 11734858, PMID: 12111250]. Mutations in Barttin gene cause Bartter syndrome 4A (BS4A), which is an autosomal recessive disorder characterised by impaired salt re-absorption in the thick ascending loop of Henle with pronounced salt wasting, hypokalemic metabolic alkalosis, and varying degrees of hypercalciuria.
