Labcorp Genetics (formerly Invitae), Labcorp RCV002701039 SCV002998937 uncertain significance Early-onset Lafora body disease 2022-03-04 criteria provided, single submitter clinical testing 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. This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 266 of the PRDM8 protein (p.Arg266Trp). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with PRDM8-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: "Probably Damaging"; Align-GVGD: "Class C0").
