Invitae | RCV000822861 | SCV000963683 | pathogenic | Marfan syndrome; Familial thoracic aortic aneurysm and aortic dissection | 2023-11-01 | criteria provided, single submitter | clinical testing | This variant, c.5076_5078del, results in the deletion of 1 amino acid(s) of the FBN1 protein (p.Arg1692del), but otherwise preserves the integrity of the reading frame. This variant is not present in population databases (gnomAD no frequency). This variant has been observed in individual(s) with Marfan syndrome (PMID: 17657824, 27146836, 32679894; Invitae). ClinVar contains an entry for this variant (Variation ID: 520496). For these reasons, this variant has been classified as Pathogenic. |

Ambry Genetics | RCV001798930 | SCV002642900 | uncertain significance | Familial thoracic aortic aneurysm and aortic dissection | 2019-08-30 | criteria provided, single submitter | clinical testing | The c.5076_5078delAAG variant (also known as p.R1692del) is located in coding exon 41 of the FBN1 gene. This variant results from an in-frame AAG deletion at nucleotide positions 5076 to 5078. This results in the in-frame deletion of an arginine at codon 1692, and is located in the TGFB#05 domain. This variant (also described as c.5074_5076delAGA) was first reported in a child with ectopia lentis and no other clinical findings of Marfan syndrome (MFS) at the time of evaluation (Comeglio P et al. Hum. Mutat., 2007 Sep;28:928). This variant has also been detected in an individual meeting clinical diagnostic criteria for MFS, as well as in his asymptomatic father (Poninska JK et al. J Transl Med, 2016 05;14:115). This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis (Choi Y et al. PLoS ONE. 2012; 7(10):e46688). Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
