How does Marfan syndrome affect the lungs?
Decreased flexibility in the air sacs of the lungs can be detected in nearly everybody with the disease, but does not pose any serious problem. One out of twenty people diagnosed with the condition experience the feeling of breathlessness or chest pain as a direct result of the spontaneous collapse of the lung (spontaneous pneumothorax). Some people with Marfan syndrome also suffer from sleep-disordered breathing.
