Invitae | RCV000793655 | SCV000933019 | uncertain significance | Fanconi anemia | 2022-09-23 | criteria provided, single submitter | clinical testing | This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 273 of the FANCD2 protein (p.Ile273Val). This variant is present in population databases (rs770985541, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with FANCD2-related conditions. ClinVar contains an entry for this variant (Variation ID: 640600). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt FANCD2 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. |

RCV001816844 | SCV002071752 | uncertain significance | not specified | 2021-07-30 | criteria provided, single submitter | clinical testing | This sequence change does not appear to have been previously described in patients with FANCD2-related disorders and has been described in the gnomAD database with a low population frequency of 0.0077% in the non-Finnish European subpopulation (dbSNP rs770985541). The p.Ile273Val change affects a poorly conserved amino acid residue located in a domain of the FANCD2 protein that is known to be functional. The p.Ile273Val substitution appears to be benign using several in-silico pathogenicity prediction tools (SIFT, PolyPhen2, Align GVGD, REVEL). Due to these contrasting evidences and the lack of functional studies, the clinical significance of the p.Ile273Val change remains unknown at this time. |
