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 MedicineAug 04, 2016The p.Pro498Ser variant in CDH23 has not been previously reported in individuals with hearing loss or Usher syndrome, but has been identified in 1/11572 Latino chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitut e.org; dbSNP rs550931640). Although this variant has been seen in the general po pulation, its frequency is not high enough to rule out a pathogenic role. Comput ational prediction tools and conservation analyses suggest that this variant may not impact the protein, though this information is not predictive enough to rul e out pathogenicity. In summary, the clinical significance of the p.Pro498Ser va riant is uncertain. -
