Labcorp Genetics (formerly Invitae), Labcorp RCV002300270 SCV002596202 uncertain significance Autosomal recessive nonsyndromic hearing loss 1A; Autosomal recessive nonsyndromic hearing loss 1B; Autosomal dominant nonsyndromic hearing loss 3B; Hidrotic ectodermal dysplasia syndrome 2022-10-08 criteria provided, single submitter clinical testing This sequence change replaces glycine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 59 of the GJB6 protein (p.Gly59Val). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with GJB6-related conditions. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt GJB6 protein function. 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.
