Labcorp Genetics (formerly Invitae), Labcorp RCV001309348 SCV001498844 uncertain significance Fanconi anemia 2019-04-24 criteria provided, single submitter clinical testing This sequence change replaces lysine with arginine at codon 228 of the FANCF protein (p.Lys228Arg). The lysine residue is weakly conserved and there is a small physicochemical difference between lysine and arginine. This variant is present in population databases (rs766802308, ExAC 0.01%). This variant has not been reported in the literature in individuals with FANCF-related conditions. 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 arginine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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.
