RCV001191605 | SCV001359479 | uncertain significance | Familial thoracic aortic aneurysm and aortic dissection | 2023-09-26 | criteria provided, single submitter | clinical testing | This missense variant replaces valine with methionine at codon 1817 of the FBN1 protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with affected with FBN1-related disorders in the literature. This variant has been identified in 3/251208 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. |

RCV003770162 | SCV004610958 | uncertain significance | Marfan syndrome; Familial thoracic aortic aneurysm and aortic dissection | 2023-12-09 | criteria provided, single submitter | clinical testing | This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 1817 of the FBN1 protein (p.Val1817Met). This variant is present in population databases (rs757901214, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with FBN1-related conditions. ClinVar contains an entry for this variant (Variation ID: 927991). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on FBN1 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. |
