Labcorp Genetics (formerly Invitae), Labcorp RCV001969133 SCV002254000 uncertain significance Fanconi anemia 2022-08-16 criteria provided, single submitter clinical testing This sequence change replaces asparagine, which is neutral and polar, with lysine, which is basic and polar, at codon 102 of the FANCB protein (p.Asn102Lys). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with FANCB-related conditions. ClinVar contains an entry for this variant (Variation ID: 1468716). 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 lysine 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.
