The FBN1 gene is associated with autosomal dominant Marfan syndrome (MedGen UID: 44287), MASS syndrome (MedGen UID: 346932), thoracic aortic aneurysms and dissections (TAAD) (MedGen UID: 468423), isolated ectopia lentis (MedGen UID: 342716), and stiff skin syndrome (MedGen UID: 348877). Other FBN1-related conditions have been reported (OMIM: 134797).

Invitae tests that include this gene:
Pathogenic FBN1 variants are associated with 70%-93% of clinical cases of Marfan syndrome and are a rare cause of TAAD.
The FBN1 gene encodes fibrillin-1, a large, extracellular matrix glycoprotein, which is a major structural component of microfibrils. Microfibrils provide a scaffold for elastin deposition for the force-bearing structural support in connective tissue throughout the body.
Invitae is a College of American Pathologists (CAP)-accredited and Clinical Laboratory Improvement Amendments (CLIA)-certified clinical diagnostic laboratory performing full-gene sequencing and deletion/duplication analysis using next-generation sequencing technology (NGS).
Our sequence analysis covers clinically important regions of each gene, including coding exons, +/- 10 base pairs of adjacent intronic sequence in the transcript listed below. In addition, analysis covers the select non-coding variants specifically defined in the table below. Any variants that fall outside these regions are not analyzed. Any specific limitations in the analysis of these genes are also listed in the table below.
Our analysis detects most intragenic deletions and duplications at single exon resolution. However, in rare situations, single-exon copy number events may not be analyzed due to inherent sequence properties or isolated reduction in data quality. If you are requesting the detection of a specific single-exon copy number variation, please contact Client Services before placing your order.
