Invitae | RCV002515210 | SCV003524816 | pathogenic | Early infantile epileptic encephalopathy with suppression bursts | 2023-08-30 | criteria provided, single submitter | clinical testing | This sequence change replaces serine, which is neutral and polar, with arginine, which is basic and polar, at codon 1362 of the SCN1A protein (p.Ser1362Arg). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with Dravet syndrome (PMID: 26096185). In at least one individual the variant was observed to be de novo. ClinVar contains an entry for this variant (Variation ID: 189942). 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 SCN1A protein function. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. For these reasons, this variant has been classified as Pathogenic. |
