Invitae RCV000538157 SCV000626374 uncertain significance Fanconi anemia 2022-11-01 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 1456 of the FANCM protein (p.Arg1456His). This variant is present in population databases (rs749332566, gnomAD 0.009%). This variant has not been reported in the literature in individuals affected with FANCM-related conditions. ClinVar contains an entry for this variant (Variation ID: 456271). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The histidine 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.
