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

The p.Asp2218Glu variant in CDH23 has not been previously reported in individual s with hearing loss, but has been identified in 0.1% (9/8502) of East Asian chro mosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.or g; dbSNP rs537236734). Although this variant has been seen in the general popula tion, its frequency is not high enough to rule out a pathogenic role. Computatio nal prediction tools and conservation analysis suggest that this variant may imp act the protein, though this information is not predictive enough to determine p athogenicity. In summary, the clinical significance of the p.Asp2218Glu variant is uncertain. -
