Invitae RCV001211292 SCV001382823 uncertain significance Congenital myasthenic syndrome 8 2022-08-16 criteria provided, single submitter clinical testing This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 319 of the AGRN protein (p.Pro319Ser). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with AGRN-related conditions. ClinVar contains an entry for this variant (Variation ID: 941502). 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"). 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.
