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 Thr46Lys variant in CDH23 has not been reported in individuals with hearing loss or Usher syndrome. Computational analyses (biochemical amino acid propertie s, conservation, AlignGVGD, PolyPhen2, and SIFT) do not provide strong support f or or against an impact to the protein. In summary, additional data is needed to determine the clinical significance of this variant. -

This sequence change replaces threonine, which is neutral and polar, with lysine, which is basic and polar, at codon 46 of the CDH23 protein (p.Thr46Lys). This variant is present in population databases (rs727504613, gnomAD 0.02%). 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: 179083). 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 not expected to disrupt 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. -
