RCV003765474 | SCV004580099 | uncertain significance | Intellectual disability, autosomal dominant 6; Developmental and epileptic encephalopathy, 27 | 2024-06-03 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 1381 of the GRIN2B protein (p.Arg1381Gln). This variant is present in population databases (rs761443441, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with GRIN2B-related conditions. ClinVar contains an entry for this variant (Variation ID: 245959). 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 GRIN2B 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. |
