<unk>  syndrome (MFS) is a rare multi-systemic genetic disorder that affects the connective tissue. Those with the condition tend to be tall and thin, with long arms, legs, fingers, and toes. They also typically have overly-flexible joints and scoliosis. The most serious complications involve the heart and aorta, with an increased risk of mitral valve prolapse and aortic aneurysm. The lungs, eyes, bones, and the covering of the spinal cord are also commonly affected. The severity of the symptoms of MFS is variable. MFS is caused by a mutation in FBN1, one of the genes that makes fibrillin, which results in abnormal connective tissue. It is an autosomal dominant disorder. About 75% of the time, the condition is inherited from a parent with the condition, while 25% of the time it is a new mutation.<unk>  is often based on the Ghent criteria. There is no known cure for MFS. Many of those with the disorder have a normal life expectancy with proper treatment. Management often includes the use of beta blockers such as propranolol or atenolol or, if they are not tolerated, calcium channel blockers or ACE inhibitors. Surgery may be required to repair the aorta or replace a heart valve. Avoiding strenuous exercise is recommended for those with the condition. About 1 in 5,000 to 1 in 10,000 people have MFS. Rates of the condition are similar in different regions of the world. It is named after French pediatrician Antoine<unk> , who first described it in 1896.
