Invitae RCV001296041 SCV001484996 pathogenic Developmental and epileptic encephalopathy, 14; Autosomal dominant nocturnal frontal lobe epilepsy 5 2021-10-08 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 KCNT1 protein function. ClinVar contains an entry for this variant (Variation ID: 999973). This missense change has been observed in individual(s) with clinical features of KCNT1-related conditions (Invitae). In at least one individual the variant was observed to be de novo. This variant is not present in population databases (ExAC no frequency). This sequence change replaces serine with asparagine at codon 379 of the KCNT1 protein (p.Ser379Asn). The serine residue is moderately conserved and there is a small physicochemical difference between serine and asparagine.
