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 threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 1083 of the CDH23 protein (p.Thr1083Met). This variant is present in population databases (rs756165682, 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: 843647). 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 C65"). 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. -
