Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine RCV000216214 SCV000271547 uncertain significance not specified 2014-12-30 criteria provided, single submitter clinical testing The p.Val1283Met variant in CDH23 has not been previously reported in individual s with hearing loss. This variant has been identified in 4/16602 of South Asian chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitu te.org). Although this variant has been seen in the general population, its freq uency is not high enough to rule out a pathogenic role. Computational predictio n tools and conservation analyses do not provide strong support for or against a n impact to the protein. In summary, the clinical significance of the p.Val1283M et variant is uncertain.

Invitae RCV000513052 SCV003520101 uncertain significance not provided 2022-06-14 criteria provided, single submitter clinical testing This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 1283 of the CDH23 protein (p.Val1283Met). This variant is present in population databases (rs758413650, gnomAD 0.03%). 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: 228481). 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 C15"). 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.
