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]

Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineJan 06, 2016The p.Asp2219Asn variant in CDH23 has previously been reported in one individual with hearing loss (LMM unpublished data). This variant has been identified in 6 /116134 of the total chromosomes in the Exome Aggregation Consortium (ExAC, http ://exac.broadinstitute.org; dbSNP rs555684781); however, this frequency is not h igh enough to rule out a pathogenic role. Computational prediction tools and con servation analyses suggest that the p.Asp2219Asn variant may impact the protein, though this information is not predictive enough to determine pathogenicity. In summary, the clinical significance of thep.Asp2219Asn variant is uncertain. -
