WebSep 17, 2014 · Paroxysmal nocturnal hemoglobinuria (PNH) is a disorder of hematopoietic stem cells that has largely been considered a monogenic disorder due to acquisition of mutations in the gene encoding PIGA, which is required for glycosylphosphatidylinositol (GPI) anchor biosynthesis. WebParoxysmal nocturnal hemoglobinuria (PNH) is a rare acquired disorder in which a somatic mutation in the Pig-A gene in a clone of bone marrow stem cell results in defective synthesis of GPI-anchored proteins. PNH is characterized clinically by intravascular hemolysis and venous thrombosis.
