Marfan syndrome has several signs and symptoms depending on the individual affected.
The main manifestations of the disease are related to the skeletal system, in which the affected individual presents with elongated limbs, elevated height, scoliosis and thoracic deformations; the cardiac system, characterized by mitral valve prolapse (closing of the upper and lower chambers of the left side of the heart) and dilation of the aorta; and the ocular system, characterized by a detachment in the lens of the eye, and myopia.
The ability of genetic defects such as Marfan syndrome to reach such distinct organs is called pleiotropy.
