Marfan syndrome is a rare disorder. It causes a defect in the body’s connective tissue. Connective tissue supports and connects many of the body's structures. As a result, Marfan syndrome affects many organ systems, including:
- Skeleton—particularly joints
- Heart and the aorta, the artery that leads from the heart
- Heart and blood vessels
