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]

Variant classified as Uncertain Significance - Favor Benign. The p.Asn434Ser var iant in CDH23 has been previously identified by our laboratory in 1 individual w ith hearing loss who did not carry a second CDH23 variant. This variant has also been identified in 0.2% (24/9802) of African chromosomes by the Exome Aggregati on Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs139287714). Althoug h this variant has been seen in the general population, its frequency is not hig h enough to rule out a pathogenic role. Computational prediction tools and conse rvation analyses suggest that this variant may impact the protein, though this i nformation is not predictive enough to determine pathogenicity. In summary, the clinical significance of this variant cannot be determined with certainty; howev er, the frequency data suggest that it is more likely to be benign. -
