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 submitter	clinical testing	GeneDx	Oct 15, 2021	Has not been previously published as pathogenic or benign to our knowledge -
Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Dec 03, 2021	This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 90 of the CDH23 protein (p.Arg90Gln). This variant is present in population databases (rs397517317, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with CDH23-related conditions. ClinVar contains an entry for this variant (Variation ID: 45899). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Not Available"; Align-GVGD: "Class C0"). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

The Arg90Gln variant in CDH23 has not been reported in the literature nor previo usly identified by our laboratory. Computational analyses (biochemical amino aci d properties, homology, PolyPhen2, SIFT, AlignGVGD) do not provide strong suppor t for or against pathogenicity. In summary, the clinical significance of this va riant cannot be determined with certainty at this time. -
