not specified Uncertain:1
The Arg1168Gln variant in CDH23 has not been previously reported in individuals with hearing loss or in large population studies. Computational analyses (bioche mical amino acid properties, conservation, AlignGVGD, PolyPhen2, and SIFT) sugge st that the Arg1168Gln variant may impact the protein, though this information i s not predictive enough to determine pathogenicity. In summary, additional info rmation is needed to determine the clinical significance of this variant. -

not provided Uncertain:1
This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 1168 of the CDH23 protein (p.Arg1168Gln). This variant is present in population databases (rs727502925, gnomAD 0.006%). 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: 162907). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt CDH23 protein function. 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. -
