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]

Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineFeb 27, 2018Variant classified as Uncertain Significance - Favor Benign. The p.Val623Ile var iant in CDH23 has been previously reported by our laboratory in the homozygous s tate in 1 individual with hearing loss with delayed walking; however, this patie nt harbored a homozygous likely pathogenic variant in another gene that explaine d the phenotype. This variant has also been identified in 0.13% (39/29954) of So uth Asian chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad. broadinstitute.org/; dbSNP rs143782870); however its frequency is not high enoug h to rule out a pathogenic role. Computational prediction tools and conservation analysis do not provide strong support for or against an impact to the protein. In summary, while the clinical significance of the p.Val623Ile variant is uncer tain, these data suggest that it is more likely to be benign. ACMG/AMP Criteria applied: BS1_P, BP5. -
