• Popis: Paroxysmal nocturnal hemoglobinuria (PNH) is caused by clonal expansion of hematopoietic stem cells that carry a somatic mutation in the X-linked gene PIG-A (phosphatidylinositol glycan anchor biosynthesis class A). The mutation leads to a deficiency of glycosylphosphatidylinositol-anchored membrane proteins. The loss of membrane-associated complement regulatory proteins CD55 and CD59 increases susceptibility of red blood cells and platelets to complement-mediated lysis, leading to hemolytic anemia, thrombophilia and reduced life expectancy in untreated patients.
