Invitae RCV001373413 SCV001570128 uncertain significance Neonatal-onset encephalopathy with rigidity and seizures 2022-10-24 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 expected to disrupt BRAT1 protein function. ClinVar contains an entry for this variant (Variation ID: 1063563). This variant has not been reported in the literature in individuals affected with BRAT1-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 120 of the BRAT1 protein (p.Arg120Cys).
