Labcorp Genetics (formerly Invitae), Labcorp RCV001965687 SCV002246620 uncertain significance Developmental and epileptic encephalopathy 94 2021-04-24 criteria provided, single submitter clinical testing 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 not expected to disrupt CHD2 protein function. This variant has been observed in individual(s) with clinical features of CHD2-related conditions (Invitae). This variant is not present in population databases (ExAC no frequency). This sequence change replaces isoleucine with valine at codon 812 of the CHD2 protein (p.Ile812Val). The isoleucine residue is highly conserved and there is a small physicochemical difference between isoleucine and valine.
