Genes affected

CLCNKA (HGNC:2026): (chloride voltage-gated channel Ka) This gene is a member of the CLC family of voltage-gated chloride channels. The encoded protein is predicted to have 12 transmembrane domains, and requires a beta subunit called barttin to form a functional channel. It is thought to function in salt reabsorption in the kidney and potassium recycling in the inner ear. The gene is highly similar to CLCNKB, which is located 10 kb downstream from this gene. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

The c.8A>C (p.E3A) alteration is located in exon 2 (coding exon 1) of the CLCNKA gene. This alteration results from a A to C substitution at nucleotide position 8, causing the glutamic acid (E) at amino acid position 3 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
