Labcorp Genetics (formerly Invitae), Labcorp RCV002519861 SCV003028844 uncertain significance Fanconi anemia 2022-06-18 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid, which is acidic and polar, with glutamine, which is neutral and polar, at codon 523 of the FANCG protein (p.Glu523Gln). This variant is present in population databases (rs761993636, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with FANCG-related conditions. ClinVar contains an entry for this variant (Variation ID: 252633). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The glutamine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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.
