GeneDx RCV001585161 SCV001818491 uncertain significance not provided 2020-03-30 criteria provided, single submitter clinical testing In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect; Not observed in large population cohorts (Lek et al., 2016); Has not been previously published as pathogenic or benign to our knowledge
Invitae RCV001585161 SCV002317628 uncertain significance not provided 2021-10-21 criteria provided, single submitter clinical testing This sequence change replaces glycine with arginine at codon 329 of the GNAS protein (p.Gly329Arg). The glycine residue is moderately conserved and there is a moderate physicochemical difference between glycine and arginine. This variant is not present in population databases (ExAC no frequency). 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: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals affected with GNAS-related conditions.
