- Marfan syndrome
- Inherited disorder characterized by long fingers and toes, dislocation of the lens, and aortic wall weakness and aneurysm. Parents with Marfan syndrome have a 50 percent chance of passing it on to each child. There is not yet a genetic test for Marfan syndrome, so diagnosis is complex. It usually includes several steps: generally a detailed medical and family history, visual examination, measurement and comparison of height to limb length, eye examination, X-rays of the spine and sometimes other areas, and electrocardiogram and echocardiogram of the heart. There is no treatment specifically for Marfan syndrome, but specific problems associated with it (such as scoliosis and eye problems) may be treated individually. (It has been suggested
