Marfan syndrome
![](https://commons.wikimedia.org/wiki/Special:FilePath/Myxomatous_aortic_valve.jpg?width=300)
Marfan syndrome (also called Marfan's syndrome) is a genetic disorder of connective tissue. It has a variable clinical presentation, ranging from mild to severe systemic disease. The most serious manifestations involve defects of the heart valves and aorta, which may lead to early death if not properly managed. The syndrome also may affect the lungs, eyes, dural sac surrounding the spinal cord, the skeleton, and the hard palate. People with Marfan syndrome tend to be unusually tall, with long limbs and long, thin fingers and toes.The syndrome is caused by the misfolding of fibrillin-1, a glycoprotein which forms elastic fibers in connective tissue and contributes to cell signaling activity by binding to and sequestering transforming growth factor beta (TGF-β). The mutated fibrillin binds poorly to TGF-β, which results in an accumulation of excess TGF-β in the lungs, heart valves, and aorta. This in turn causes abnormal structure and function of vascular smooth muscle and reduced integrity of the extracellular matrix, which weaken the tissues and cause the features of Marfan syndrome.Named after Antoine Marfan, the French pediatrician who first described the condition in 1896, the disease is an autosomal dominant disorder. Management often includes the use of angiotensin II receptor antagonists (ARBs) and beta blockers.
