Invitae RCV000547145 SCV000653931 uncertain significance Congenital myasthenic syndrome 8 2017-02-13 criteria provided, single submitter clinical testing In summary, this variant is a novel missense change with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). While this variant is not present in population databases, the frequency information is unreliable, as metrics indicate poor data quality at this position in the ExAC database. This variant has not been reported in the literature in individuals with an AGRN-related disease. This sequence change replaces arginine with cysteine at codon 1395 of the AGRN protein (p.Arg1395Cys). The arginine residue is highly conserved and there is a large physicochemical difference between arginine and cysteine.
