Labcorp Genetics (formerly Invitae), Labcorp RCV005200649 SCV005835331 uncertain significance Noonan syndrome 9 2024-10-24 criteria provided, single submitter clinical testing This sequence change replaces serine, which is neutral and polar, with proline, which is neutral and non-polar, at codon 631 of the SOS2 protein (p.Ser631Pro). This variant is present in population databases (no rsID available, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with SOS2-related conditions. Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on SOS2 protein function. 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.
