Labcorp Genetics (formerly Invitae), Labcorp RCV002520612 SCV003299346 uncertain significance not provided 2024-10-23 criteria provided, single submitter clinical testing This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 149 of the CDH23 protein (p.Thr149Met). This variant is present in population databases (rs370947344, gnomAD 0.01%). 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: 300401). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on 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.
