Genes affected
CLCN5 (HGNC:2023): (chloride voltage-gated channel 5) This gene encodes a member of the ClC family of chloride ion channels and ion transporters. The encoded protein 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.

This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 30 of the CLCN5 protein (p.Arg30Trp). This variant is present in population databases (rs200225080, gnomAD 0.02%). This missense change has been observed in individual(s) with hypophosphatemic rickets (PMID: 29758562). This variant is also known as c.298C>T, p.Arg100Trp. ClinVar contains an entry for this variant (Variation ID: 2152346). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
