Labcorp Genetics (formerly Invitae), Labcorp RCV002003946 SCV002279453 uncertain significance Noonan syndrome 9 2021-11-24 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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals affected with SOS2-related conditions. This variant is present in population databases (rs775139330, gnomAD 0.007%). This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 757 of the SOS2 protein (p.Pro757Ser).
