This gene encodes an essential beta subunit for CLC chloride channels. These heteromeric channels localize to basolateral membranes of renal tubules and of potassium-secreting epithelia of the inner ear. Mutations in this gene have been associated with Bartter syndrome with sensorineural deafness. Synonyms: Polyclonal BSND antibody, Anti-BSND antibody, Bartter syndrome, infantile, with sensorineural deafness, Barttin antibody, BART antibody, DFNB73 antibody, MGC119283 antibody, MGC119284 antibody, MGC119285 antibody.
