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]

Collection Method: clinical testing

This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 1290 of the CDH23 protein (p.Pro1290Leu). This variant is present in population databases (rs377222292, gnomAD 0.04%). 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: 162909). An algorithm developed to predict the effect of missense changes on protein structure and function outputs the following: PolyPhen-2: "Not Available". The leucine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect 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. -

Variant classified as Uncertain Significance - Favor Benign. The Pro1290Leu vari ant in CDH23 has not been reported in individuals with hearing loss, but has bee n identified in 0.02% (1/4234) of African American chromosomes by the NHLBI Exom e Sequencing Project (http://evs.gs.washington.edu/EVS/; dbSNP rs377222292). Com putational analyses (biochemical amino acid properties, conservation, AlignGVGD, PolyPhen2, and SIFT) suggest that the Pro1290Leu variant may not impact the pro tein, though this information is not predictive enough to rule out pathogenicity . In summary, the clinical significance of this variant cannot be determined wit h certainty; however based upon the computational data, we would lean towards a more likely benign role. -
