CLCN5 encodes a member of the ClC family of chloride ion channels and ion transporters. The Chloride Voltage-Gated Channel 5 is primarily localized to endosomal membranes and may function to facilitate albumin uptake by the renal proximal tubule. Mutations in this gene have been found in Dent disease and renal tubular disorders complicated by nephrolithiasis. Alternatively spliced transcript variants have been found for this gene.
