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]

The c.6637G>A (p.G2213S) alteration is located in exon 48 (coding exon 47) of the CDH23 gene. This alteration results from a G to A substitution at nucleotide position 6637, causing the glycine (G) at amino acid position 2213 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Gly2213Ser in Exon 48 of CDH23: This variant is not expected to have clinical s ignificance because the glycine (Gly) residue at position 2213 is not conserved through species, with many mammals having a serine (Ser). In addition, this var iant has been identified in 0.01% (1/8522) of European American chromosomes by t he NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/EVS/; dbSNP rs37 5900265). -
