Invitae | RCV000461194 | SCV000547744 | uncertain significance | Fanconi anemia | 2019-02-27 | criteria provided, single submitter | clinical testing | This sequence change replaces glycine with arginine at codon 16 of the FANCA protein (p.Gly16Arg). The glycine residue is weakly conserved and there is a moderate physicochemical difference between glycine and arginine. While this variant is not present in population databases (no rsID), the frequency information is unreliable, as metrics indicate poor data quality at this position in the ExAC database. This variant has not been reported in the literature in an individual with a FANCA-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; 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. In summary, this variant is a novel missense change that is not predicted to affect protein function. There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance. |
