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]

2290-13delT in intron 21 of CDH23: This variant is not expected to have clinical significance because it has been identified in 2.32% (90/3876) of African Ameri can chromosomes by the NHLBI Exome Sequencing Project and 2.5% (9/490) of Africa n and African American (ASW, LWK, YRI) chromosomes by the 1000 Genomes Project ( http://evs.gs.washington.edu/EVS/; dbSNP 202233569). In addition, a deletion of a T nucleotide at this position does not diverge from the splice consensus sequ ence and is therefore unlikely to impact splicing. -
