Genes affected

CDH23 (HGNC:13733): (cadherin related 23) This gene is a member of the cadherin superfamily, whose genes encode calcium dependent cell-cell adhesion glycoproteins. The encoded protein is thought to be involved in stereocilia organization and hair bundle formation. The gene is located in a region containing the human deafness loci DFNB12 and USH1D. Usher syndrome 1D and nonsyndromic autosomal recessive deafness DFNB12 are caused by allelic mutations of this cadherin-like gene. Upregulation of this gene may also be associated with breast cancer. Alternative splice variants encoding different isoforms have been described. [provided by RefSeq, May 2013]

The Arg834Cys variant in CDH23 has not been previously reported in individuals w ith hearing loss, but has been identified in 0.023% (2/8538) of European America n chromosomes by the NHLBI Exome Sequencing Project (http://evs.gs.washington.ed u/EVS/; dbSNP rs372387390). Although this variant has been seen in the general p opulation, its frequency is not high enough to rule out a pathogenic role. Compu tational prediction tools and conservation analyses suggest that the Arg834Cys v ariant may impact the protein, though this information is not predictive enough to determine pathogenicity. In summary, the clinical significance of the Arg834C ys variant is uncertain. -

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 834 of the CDH23 protein (p.Arg834Cys). This variant is present in population databases (rs372387390, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with CDH23-related conditions. ClinVar contains an entry for this variant (Variation ID: 179700). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on CDH23 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. -
