Labcorp Genetics (formerly Invitae), Labcorp RCV000630874 SCV000751845 uncertain significance Fanconi anemia 2018-01-02 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals with FANCG-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces threonine with alanine at codon 550 of the FANCG protein (p.Thr550Ala). The threonine residue is weakly conserved and there is a small physicochemical difference between threonine and alanine. 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 alanine 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.
