Labcorp Genetics (formerly Invitae), Labcorp RCV001994280 SCV002274373 uncertain significance Rhabdoid tumor predisposition syndrome 2 2020-12-08 criteria provided, single submitter clinical testing This sequence change replaces leucine with methionine at codon 409 of the SMARCA4 protein (p.Leu409Met). The leucine residue is highly conserved and there is a small physicochemical difference between leucine and methionine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with SMARCA4-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: "Deleterious"; 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.
