not provided Uncertain:2
Not observed at significant frequency in large population cohorts (Lek et al., 2016); In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge; This variant is associated with the following publications: (PMID: 27535533) -
This sequence change replaces glutamine with arginine at codon 562 of the CDH23 protein (p.Gln562Arg). The glutamine residue is highly conserved and there is a small physicochemical difference between glutamine and arginine. This variant is present in population databases (rs397517311, ExAC 0.009%). 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: 45881). 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"). 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. -
not specified Uncertain:1
The Gln562Arg variant in CDH23 has not been reported in the literature nor previ ously identified by our laboratory. Computational analyses (biochemical amino ac id properties, conservation, AlignGVGD, PolyPhen2, and SIFT) do not provide stro ng support for or against an impact to the protein. In summary, the clinical sig nificance of this variant cannot be determined with certainty. -
