Answer

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare, chronic, debilitating disorder that most frequently presents in early adulthood and usually continues throughout the patient's life. PNH results in the death of approximately 50% of affected individuals due to thrombotic complications and, until recently, had no specific therapy.
