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]

This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 1283 of the CDH23 protein (p.Val1283Met). This variant is present in population databases (rs758413650, gnomAD 0.03%). 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: 228481). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Not Available"; Align-GVGD: "Class C15"). 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. -

The p.Val1283Met variant in CDH23 has not been previously reported in individual s with hearing loss. This variant has been identified in 4/16602 of South Asian chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitu te.org). Although this variant has been seen in the general population, its freq uency is not high enough to rule out a pathogenic role. Computational predictio n tools and conservation analyses do not provide strong support for or against a n impact to the protein. In summary, the clinical significance of the p.Val1283M et variant is uncertain. -
