Invitae RCV001202451 SCV001373563 uncertain significance Congenital myasthenic syndrome 8 2022-08-16 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 841 of the AGRN protein (p.Arg841Gln). This variant is present in population databases (rs756103278, gnomAD 0.003%). 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"). ClinVar contains an entry for this variant (Variation ID: 934115). This variant has not been reported in the literature in individuals affected with AGRN-related conditions.
GeneDx RCV002462354 SCV002757209 uncertain significance not provided 2022-05-27 criteria provided, single submitter clinical testing Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge
