Labcorp Genetics (formerly Invitae), Labcorp RCV002833009 SCV003207307 uncertain significance Hepatic veno-occlusive disease-immunodeficiency syndrome 2022-11-01 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. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0". The glutamic acid amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. This variant has not been reported in the literature in individuals affected with SP110-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.007%). This sequence change replaces lysine, which is basic and polar, with glutamic acid, which is acidic and polar, at codon 294 of the SP110 protein (p.Lys294Glu).
