PAP or Pulmonary Alveolar Proteinosis is a rare disorder of the lungs that is caused by the concentration of grainy substance in the lungs. The macrophages that swallow and removes protein and phospholipids from the lungs cease to work properly and makes breathing troublesome, since the lung cannot absorb adequate oxygen from the air. The disease has been linked to mutations in the gene and defects in the growth factor receptor. The common symptoms include breathlessness, cough, coughing up of whitish phlegm and even blood in rare cases.
