Invitae | RCV000696824 | SCV000825403 | uncertain significance | Developmental and epileptic encephalopathy, 14; Autosomal dominant nocturnal frontal lobe epilepsy 5 | 2023-05-03 | criteria provided, single submitter | clinical testing | 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 not expected to disrupt KCNT1 protein function. ClinVar contains an entry for this variant (Variation ID: 574798). This variant has not been reported in the literature in individuals affected with KCNT1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 812 of the KCNT1 protein (p.Asn812Ser). |
