Labcorp Genetics (formerly Invitae), Labcorp RCV001243902 SCV001417089 likely pathogenic Marfan syndrome; Familial thoracic aortic aneurysm and aortic dissection 2019-11-15 criteria provided, single submitter clinical testing This sequence change affects a donor splice site in intron 15 of the FBN1 gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product. This variant is not present in population databases (ExAC no frequency). This variant has been observed in individual(s) with clinical features of Marfan syndrome (Invitae). Donor and acceptor splice site variants typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in FBN1 are known to be pathogenic (PMID: 17657824, 19293843). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.
