Labcorp Genetics (formerly Invitae), Labcorp RCV003850444 SCV004654634 uncertain significance CHARGE syndrome 2024-04-02 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 776 of the CHD7 protein (p.Asp776Gly). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with CHD7-related conditions. 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 not expected to disrupt CHD7 protein function with a negative predictive value of 95%. 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.
