Labcorp Genetics (formerly Invitae), Labcorp RCV001317736 SCV001508406 uncertain significance Developmental and epileptic encephalopathy 94 2020-09-15 criteria provided, single submitter clinical testing 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 not been reported in the literature in individuals with CHD2-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces valine with glycine at codon 1378 of the CHD2 protein (p.Val1378Gly). The valine residue is highly conserved and there is a moderate physicochemical difference between valine and glycine. 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.
