Labcorp Genetics (formerly Invitae), Labcorp RCV001928819 SCV002201043 uncertain significance Noonan syndrome 9 2021-04-23 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals with SOS2-related conditions. 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: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available"). 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. The frequency data for this variant in the population databases is not available, as this variant may be reported as separate entries in the ExAC database. This sequence change replaces asparagine with serine at codon 744 of the SOS2 protein (p.Asn744Ser). The asparagine residue is highly conserved and there is a small physicochemical difference between asparagine and serine.
