Genes affected

SOS2 (HGNC:11188): (SOS Ras/Rho guanine nucleotide exchange factor 2) This gene encodes a regulatory protein that is involved in the positive regulation of ras proteins. Mutations in this gene are associated with Noonan Syndrome-9. [provided by RefSeq, Jul 2016]

This variant has not been reported in the literature in individuals affected with SOS2-related conditions. 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 SOS2 protein function. ClinVar contains an entry for this variant (Variation ID: 475742). This variant is present in population databases (rs768829374, gnomAD 0.003%). This sequence change replaces glutamic acid, which is acidic and polar, with glutamine, which is neutral and polar, at codon 710 of the SOS2 protein (p.Glu710Gln). -
