Labcorp Genetics (formerly Invitae), Labcorp RCV002008240 SCV002270994 uncertain significance Fanconi anemia complementation group E 2021-10-11 criteria provided, single submitter clinical testing This sequence change replaces leucine with phenylalanine at codon 63 of the FANCE protein (p.Leu63Phe). The leucine residue is weakly conserved and there is a small physicochemical difference between leucine and phenylalanine. 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 phenylalanine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. This variant has not been reported in the literature in individuals affected with FANCE-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate insufficient coverage at this position in the ExAC database.
