Marfan syndrome is an inherited disorder that causes problems in the connective tissues of the blood vessels, heart, and eyes, and affects the muscles, ligaments, bones, and tendons. People with Marfan syndrome tend to be tall and thin with long arms, legs, fingers, and toes.

Marfan syndrome may cause heart or aorta problems, a curved spine, vision trouble, and pain if the nerves are affected. Some people may have mild problems. But others have more serious symptoms.

Treatment for Marfan syndrome includes treating specific problems related to the connective tissue disease, such as heart problems.
