CHEO Genetics Diagnostic Laboratory, Children's Hospital of Eastern Ontario RCV001799395 SCV002041947 uncertain significance Familial thoracic aortic aneurysm and aortic dissection 2020-03-17 criteria provided, single submitter clinical testing
Labcorp Genetics (formerly Invitae), Labcorp RCV002544365 SCV003471621 uncertain significance Marfan syndrome; Familial thoracic aortic aneurysm and aortic dissection 2022-10-14 criteria provided, single submitter clinical testing This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 339 of the FBN1 protein (p.Ala339Thr). This variant is not present in population databases (gnomAD no frequency). 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: 1329352). 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) performed at Invitae indicates that this missense variant is not expected to disrupt 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.
