Paroxysmal nocturnal hemoglobinuria (PNH) definition and facts.

PNH is due to a spontaneous mutation in gene material. PNH is not inherited.
Paroxysmal nocturnal hemoglobinuria (PNH) is a rare, acquired, life-threatening disease of the blood. The disease is characterized by destruction of red blood cells (hemolytic anemia), blood clots (thrombosis), impaired bone marrow function, and a 3 to 5% risk of developing leukemia.imilarly, the risk developing PNH after treatment for aplastic anemia with immunosuppressive therapy (anti-thymocyte globulin and cyclosporine) is approximately 20 to 30%. The median survival after diagnosis is 10 years; however, some patients can survive for decades with only minor symptoms.
