Marfan syndrome is a life-threatening genetic disorder of the body's connective tissue. It affects the heart and blood vessels, the bones and the eyes. Knowing the signs is the key to early and accurate diagnosis and life-saving treatment. The Marfan Foundation creates a brighter future for everyone affected by Marfan syndrome and related disorders. We work tirelessly to advance research, serve as a resource for families and healthcare providers, and raise public awareness. We will not rest until we have achieved victory.
