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 Arg724His variant in CDH23 has not been previously reported in individuals w ith hearing loss, but has been identified in 0.03% (1/3864) of African American chromosomes by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/ EVS/; dbSNP rs374955091). Although this variant has been seen in the general pop ulation, its frequency is not high enough to rule out a pathogenic role. Computa tional prediction tools and conservation analyses suggest that the Arg724His var iant may impact the protein, though this information is not predictive enough to determine pathogenicity. In summary, the clinical significance of the Arg724His variant is uncertain -
