Gene Gene information from NCBI Gene database.
Entrez ID 7809
Gene name Barttin CLCNK type accessory subunit beta
Gene symbol BSND
Synonyms (NCBI Gene)
BARTDFNB73
Chromosome 1
Chromosome location 1p32.3
Summary 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 Ba
