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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineMay 02, 2016The p.Arg2222Cys variant in CDH23 has not been previously reported in individual s with hearing loss or Usher syndrome, but has been identified in 5/63898 Europe an chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinsti tute.org; dbSNP rs761082272). Although this variant has been seen in the genera l population, its frequency is not high enough to rule out a pathogenic role. Th e arginine (Arg) at position 2222 is not highly conserved in mammals and evoluti onary distant species, and one mammal (Chinese hamster) carries a cysteine (Cys) at this position, raising the possibility that this change at this position may be tolerated. Additional computational prediction tools do not provide strong s upport for or against an impact to the protein. In summary, the clinical signif icance of this variant is uncertain. -
