Labcorp Genetics (formerly Invitae), Labcorp RCV003783634 SCV004570875 pathogenic Marfan syndrome; Familial thoracic aortic aneurysm and aortic dissection 2023-07-11 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Cys1977*) in the FBN1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in FBN1 are known to be pathogenic (PMID: 17657824, 19293843). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with FBN1-related conditions (PMID: 26787436). For these reasons, this variant has been classified as Pathogenic.
