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.

ACMG classification

Verdict is Pathogenic. Variant got 11 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant X-50086551-G-A is Pathogenic according to our data. Variant chrX-50086551-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 11803.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chrX-50086551-G-A is described in Lovd as [Pathogenic].
