Labcorp Genetics (formerly Invitae), Labcorp RCV003498468 SCV004317286 uncertain significance CHARGE syndrome 2023-08-27 criteria provided, single submitter clinical testing This variant is not present in population databases (gnomAD no frequency). 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. 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 CHD7 protein function. This variant has not been reported in the literature in individuals affected with CHD7-related conditions. This sequence change replaces arginine, which is basic and polar, with leucine, which is neutral and non-polar, at codon 1620 of the CHD7 protein (p.Arg1620Leu).
