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]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant classified as Uncertain Significance - Favor Benign. The c.7055-15G>A va riant in CDH23 has not been previously reported in individuals with hearing loss , but has been identified in 1/109340 European chromosomes by the Genome Aggrega tion Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs371872394). Alt hough this variant has been seen in the general population, its frequency is not high enough to rule out a pathogenic role. This variant is located in the 3' sp lice region. Computational tools do not suggest an impact to splicing. Furthermo re, this nucleotide is not conserved with two mammals (prairie vole and ferret) having an adenine (A) at this position. However, this information is not predict ive enough to rule out pathogenicity. In summary, while the clinical significanc e of the c.7055-15G>A variant is uncertain, the splicing and conservation data s uggest it is more likely to be benign.

Illumina Laboratory Services, Illumina

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance.
