Genes affected

CLCN6 (HGNC:2024): (chloride voltage-gated channel 6) This gene encodes a member of the voltage-dependent chloride channel protein family. Members of this family can function as either chloride channels or antiporters. This protein is primarily localized to late endosomes and functions as a chloride/proton antiporter. Alternate splicing results in both coding and non-coding variants. Additional alternately spliced variants have been described but their full-length structure is unknown.

CLCN6 Gene-Disease associations (from GenCC):

• neurodegeneration, childhood-onset, with hypotonia, respiratory insufficiency, and brain imaging abnormalities

  Inheritance: AD Classification: STRONG, LIMITED Submitted by: Labcorp Genetics (formerly Invitae), G2P, Ambry Genetics

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.86).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.231 is higher than 0.05.
