Ambry Genetics | RCV001525147 | SCV000319365 | uncertain significance | Familial thoracic aortic aneurysm and aortic dissection | 2019-02-26 | criteria provided, single submitter | clinical testing | The c.5776_5778delAAT variant (also known as p.N1926del) is located in coding exon 46 of the FBN1 gene. This variant results from an in-frame deletion of 3 nucleotides at positions 5776 to 5778, causing the removal of a well-conserved asparagine residue at codon 1926. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |

RCV001525147 | SCV001735189 | uncertain significance | Familial thoracic aortic aneurysm and aortic dissection | 2023-11-03 | criteria provided, single submitter | clinical testing | This variant causes a deletion of asparagine at codon 1926 of the FBN1 protein. To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with FBN1-related disorders in the literature. This variant has been identified in 1/251088 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. |

RCV001854976 | SCV002189863 | uncertain significance | Marfan syndrome; Familial thoracic aortic aneurysm and aortic dissection | 2023-09-10 | criteria provided, single submitter | clinical testing | 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. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. ClinVar contains an entry for this variant (Variation ID: 263883). This variant has not been reported in the literature in individuals affected with FBN1-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.0009%). This variant, c.5776_5778del, results in the deletion of 1 amino acid(s) of the FBN1 protein (p.Asn1926del), but otherwise preserves the integrity of the reading frame. |

RCV003995697 | SCV004814630 | uncertain significance | Marfan syndrome | 2023-12-13 | criteria provided, single submitter | clinical testing | This variant causes an in-frame deletion of one amino acid of the FBN1 protein. To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with cardiovascular disorders in the literature. This variant has been identified in 1/251088 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. |
