Labcorp Genetics (formerly Invitae), Labcorp RCV001040170 SCV001203731 uncertain significance RASopathy 2020-12-13 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 SOS1 protein function. This variant has not been reported in the literature in individuals with SOS1-related conditions. ClinVar contains an entry for this variant (Variation ID: 838591). This variant is not present in population databases (ExAC no frequency). This sequence change replaces histidine with glutamine at codon 700 of the SOS1 protein (p.His700Gln). The histidine residue is highly conserved and there is a small physicochemical difference between histidine and glutamine.
