RCV001934510 | SCV002134243 | uncertain significance | Fanconi anemia | 2023-11-25 | criteria provided, single submitter | clinical testing | This sequence change replaces isoleucine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 777 of the FANCB protein (p.Ile777Met). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with FANCB-related conditions. ClinVar contains an entry for this variant (Variation ID: 1362633). 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 FANCB protein function with a negative predictive value of 80%. 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. |

RCV003892900 | SCV004717794 | uncertain significance | FANCB-related disorder | 2023-11-21 | no assertion criteria provided | clinical testing | The FANCB c.2331A>G variant is predicted to result in the amino acid substitution p.Ile777Met. To our knowledge, this variant has not been reported in the literature or in a large population database, indicating this variant is rare. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. |
