Labcorp Genetics (formerly Invitae), Labcorp RCV000471456 SCV000544863 uncertain significance Marfan syndrome; Familial thoracic aortic aneurysm and aortic dissection 2021-10-03 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. This variant disrupts the p.Gly585 amino acid residue in FBN1. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 19802897; Invitae). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. This sequence change replaces glycine with alanine at codon 585 of the FBN1 protein (p.Gly585Ala). The glycine residue is highly conserved and there is a small physicochemical difference between glycine and alanine. This variant is not present in population databases (ExAC no frequency). This missense change has been observed in individual(s) with clinical features of FBN1-related conditions (Invitae). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0").
