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]

p.Ser395Ser in exon 13 of CDH23: This variant is not expected to have clinical s ignificance because it does not alter an amino acid residue, is not located near a splice junction and has been identified in 0.2% (19/9594) of African chromoso mes by the Exome Aggregation Consortium (http://exac.broadinstitute.org/variant/ ; rs185105210). In addition, this variant is listed as presumed neutral in one publication (Oshima 2008). -
