Invitae | RCV000636356 | SCV000757795 | pathogenic | Early infantile epileptic encephalopathy with suppression bursts | 2022-06-27 | 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 SCN1A protein function. ClinVar contains an entry for this variant (Variation ID: 68602). This variant is also known as Val934Ala. This missense change has been observed in individual(s) with Dravet syndrome and intractable epilepsy (PMID: 14738421, 23195492). 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 valine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 944 of the SCN1A protein (p.Val944Ala). |
