Marfan syndrome is a heritable condition that affects the connective tissue. The primary purpose of connective tissue is to hold the body together and provide a framework for growth and development. In Marfan syndrome, the connective tissue is defective and does not act as it should. Because connective tissue is found throughout the body, Marfan syndrome can affect many body systems, including the skeleton, eyes, heart and blood vessels, nervous system, skin, and lungs.


... Marfan syndrome is an inherited disorder of connective tissue, the tissue that provides support to structures of the body such as blood vessel walls, heart valves, and cartilage.

The symptoms and characteristics of Marfan syndrome vary widely in severity and timing of onset. Some people have only mild symptoms, while others experience serious medical problems.

Marfan syndrome mainly affects the heart, blood vessels, skeleton, and eyes. Affected individuals often are tall and thin, and may have long and slender fingers, an arm span that exceeds body height, unusually flexible joints, and a long, narrow face, with a high roof of the mouth and crowded teeth. Nearly two-thirds of people with Marfan syndrome experience curvature of the spine (scoliosis) and have either a sunken or barrel chest. In approximately half of Marfan patients, the lens of one or both eyes is dislocated or off center. Nearsightedness and cataracts (clouding of the lens) are other common problems.

Most people with Marfan syndrome have abnormalities associated with the heart and blood vessels. Leaks in heart valves can cause shortness of breath, fatigue, and a fast, irregular heartbeat. The aorta, the large blood vessel that carries blood from the heart to the rest of the body, can weaken and stretch. An abnormal bulging (called an aneurysm) may develop in the weakened aorta. If the aorta tears or ruptures, it causes serious heart problems or sometimes sudden death. ...
