RCV001244148 | SCV001417350 | uncertain significance | Fanconi anemia | 2021-08-24 | criteria provided, single submitter | clinical testing | This sequence change replaces isoleucine with leucine at codon 191 of the FANCC protein (p.Ile191Leu). The isoleucine residue is weakly conserved and there is a small physicochemical difference between isoleucine and leucine. This variant is present in population databases (rs752429169, ExAC 0.002%). This variant has not been reported in the literature in individuals affected with FANCC-related conditions. 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 leucine 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. |

Ambry Genetics | RCV002348829 | SCV002650624 | uncertain significance | Hereditary cancer-predisposing syndrome | 2024-03-01 | criteria provided, single submitter | clinical testing | The p.I191L variant (also known as c.571A>C), located in coding exon 6 of the FANCC gene, results from an A to C substitution at nucleotide position 571. The isoleucine at codon 191 is replaced by leucine, an amino acid with highly similar properties. This amino acid position is poorly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
