Therefore, this variant has been classified as Likely Pathogenic. This variant disrupts the p.Ser257 amino acid residue in RAF1. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 17603482, 17603483, 20052757, 22389993, 23877478). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. 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 RAF1 protein function. ClinVar contains an entry for this variant (Variation ID: 618340). This variant has not been reported in the literature in individuals affected with RAF1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces serine, which is neutral and polar, with threonine, which is neutral and polar, at codon 257 of the RAF1 protein (p.Ser257Thr).
