Marfan syndrome is an inherited disorder that affects connective tissue, which supports and anchors your organs and other structures in your body. Because connective tissue is such an integral part of your body, Marfan syndrome may disrupt development and function in several sites. Most common are your heart, eyes, blood vessels and skeleton.

People with Marfan syndrome are usually tall and thin with disproportionately long arms, legs, fingers and toes. Marfan syndrome is caused by a dominant gene, which means one of your parents also has the gene and passed it to you.
