What is Marfan syndrome?
Marfan syndrome is a genetic disorder of the connective tissue of the body. Connective tissue gives strength and flexibility to many of the body's structures. The organ systems that are most often impacted in Marfan syndrome are the heart, the skeletal system, and the eyes. Marfan syndrome can also affect the skin and lungs. Although many parts of the body are made of connective tissue, the severity and onset of symptoms of Marfan syndrome varies widely from one individual to another.
