Marfan Syndrome

Community, Stories & Info

Marfan syndrome is a genetic condition that affects the body’s connective tissues, which are proteins that support the bones, blood vessels, skin and other organs. Marfan syndrome is caused by a defect in how the body makes a certain protein called fibrillin-1, and leads to problems in the connective tissues in the heart, blood vessels, joints, bones, and eyes, as well as other parts of the body. Symptoms vary from mild to life-threatening and signs often include a very tall and thin stature and loose joints.
