Invitae RCV001908529 SCV002167447 uncertain significance Intellectual disability, autosomal dominant 6; Developmental and epileptic encephalopathy, 27 2021-04-20 criteria provided, single submitter clinical testing This variant is not present in population databases (ExAC no frequency). This sequence change replaces proline with leucine at codon 582 of the GRIN2B protein (p.Pro582Leu). The proline residue is highly conserved and there is a moderate physicochemical difference between proline and leucine. This variant has not been reported in the literature in individuals with GRIN2B-related conditions. 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 GRIN2B protein function.
