Labcorp Genetics (formerly Invitae), Labcorp RCV001215964 SCV001387734 uncertain significance Fanconi anemia 2022-12-13 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: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The tyrosine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. ClinVar contains an entry for this variant (Variation ID: 945343). This variant has not been reported in the literature in individuals affected with FANCM-related conditions. This variant is present in population databases (rs752914487, gnomAD 0.06%). This sequence change replaces cysteine, which is neutral and slightly polar, with tyrosine, which is neutral and polar, at codon 921 of the FANCM protein (p.Cys921Tyr).
