Your body’s connective tissues bind and support important structures like cells and organs. These tissues break down over time in people with Marfan syndrome and similar disorders. This can lead to damage in vital organs and other structures.
Two of the most dangerous complications are aortic aneurysm and aortic dissection. An aortic aneurysm results when one of the body’s main blood vessels, the aorta, becomes weak and enlarged. Eventually, the aorta can tear or dissect, which is life-threatening.
Marfan, Loeys-Dietz, Ehlers-Danlos syndrome and the more severe Vascular Ehlers-Danlos syndrome, and other connective tissue disorders are congenital, meaning they are present from birth. Many people have a mix of common physical characteristics, including being very tall and having long limbs and fingers, crowded teeth, and flat feet. However, not everyone has these signs, and many people do not experience symptoms and/or are not diagnosed until later in life.
