RCV001996025 | SCV002275996 | likely pathogenic | Landau-Kleffner syndrome | 2022-09-13 | criteria provided, single submitter | clinical testing | In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Experimental studies have shown that this missense change affects GRIN2A function (PMID: 27839871). 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 GRIN2A protein function. ClinVar contains an entry for this variant (Variation ID: 1483207). This missense change has been observed in individuals with clinical features of GRIN2A-related conditions (PMID: 23933819; Invitae). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces lysine, which is basic and polar, with glutamic acid, which is acidic and polar, at codon 772 of the GRIN2A protein (p.Lys772Glu). |
