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]

This sequence change creates a premature translational stop signal (p.Arg1081*) in the CDH23 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in CDH23 are known to be pathogenic (PMID: 11138009, 21940737). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with deafness (PMID: 20613545). This variant is also known as p.R1086X. ClinVar contains an entry for this variant (Variation ID: 521399). For these reasons, this variant has been classified as Pathogenic. -
