RCV001211933 | SCV001383501 | uncertain significance | Early infantile epileptic encephalopathy with suppression bursts | 2024-08-29 | criteria provided, single submitter | clinical testing | This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 1195 of the SCN8A protein (p.Val1195Met). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with SCN8A-related conditions (PMID: 34431999). ClinVar contains an entry for this variant (Variation ID: 942029). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt SCN8A protein function with a positive predictive value of 80%. 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. |
