RCV001889037 | SCV002155901 | uncertain significance | RASopathy | 2021-06-01 | criteria provided, single submitter | clinical testing | This sequence change replaces isoleucine with methionine at codon 755 of the BRAF protein (p.Ile755Met). The isoleucine residue is moderately conserved and there is a small physicochemical difference between isoleucine and methionine. 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 BRAF protein function. This variant has not been reported in the literature in individuals with BRAF-related conditions. This variant is present in population databases (rs763340034, ExAC 0.01%). |
