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 MedicineOct 18, 2016The c.1450-10G>A variant in CDH23 has not been previously reported in individual s with hearing loss or Usher syndrome. It has been identified in 4/66404 Europe an chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinsti tute.org; dbSNP rs751220612); however, its frequency is not high enough to rule out a pathogenic role. This variant is located in the 3' splice region. Computat ional tools do not suggest an impact to splicing. However, this information is n ot predictive enough to rule out pathogenicity. In summary, the clinical signifi cance of the c.1450-10G>A variant is uncertain. -
