Labcorp Genetics (formerly Invitae), Labcorp RCV003806161 SCV004589462 uncertain significance Seizures, benign familial infantile, 3; Developmental and epileptic encephalopathy, 11 2023-02-16 criteria provided, single submitter clinical testing This variant is not present in population databases (gnomAD no frequency). 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. 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 SCN2A protein function. This variant has not been reported in the literature in individuals affected with SCN2A-related conditions. This sequence change replaces isoleucine, which is neutral and non-polar, with asparagine, which is neutral and polar, at codon 1676 of the SCN2A protein (p.Ile1676Asn).
