Answer:  Marfan's Syndrome is an inherited disorder of connective tissue. There are mary variations and no definitive test. In full form, patients tend to be long and angular(Abraham Lincoln was possibly a Marfan's), the joints are long and very flexible. Complications arise from dilation of the aortic root(outflow from the heart) and death from aortic root disease/dissection/aortic insufficiency. If the patient looks Marfanoid and does not have aortic root dilation. There are usually few problems. Most of the symptoms center on the aortic insufficiency and aortic root disease found in this syndrome.
