Labcorp Genetics (formerly Invitae), Labcorp RCV003032810 SCV003330981 pathogenic Intellectual disability, autosomal dominant 6; Developmental and epileptic encephalopathy, 27 2022-06-22 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. 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. This missense change has been observed in individual(s) with clinical features of GRIN2B-related conditions (PMID: 28377535). In at least one individual the variant was observed to be de novo. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces serine, which is neutral and polar, with arginine, which is basic and polar, at codon 541 of the GRIN2B protein (p.Ser541Arg).
GeneDx RCV004721101 SCV005326703 pathogenic not provided 2023-11-20 criteria provided, single submitter clinical testing In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Not observed at significant frequency in large population cohorts (gnomAD); Has not been previously published as pathogenic or benign to our knowledge; This variant is associated with the following publications: (PMID: 28377535)
