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 Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.84).
• BP6: Variant X-50072195-G-T is Benign according to our data. Variant chrX-50072195-G-T is described in ClinVar as [Likely_benign]. Clinvar id is 1223211.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00918 (1027/111892) while in subpopulation NFE AF= 0.015 (799/53129). AF 95% confidence interval is 0.0142. There are 5 homozygotes in gnomad4. There are 271 alleles in male gnomad4 subpopulation. Median coverage is 23. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 5 XL gene
