WebParoxysmal nocturnal hemoglobinemia (PNH) is a hematopoietic stem cell disorder that arises from a mutation of the phosphatidylinositol glycan-class A (PIG-A) gene, which is located on the X chromosome. The abnormal gene occurs in somatic cells, especially hematopoietic stem cells, but not in germ cells, making PNH an acquired disorder. WebFLAER Paroxysmal nocturnal hemoglobinuria (PNH) is a stem cell disorder caused by a mutation of the gene involved in the synthesis of the GPI (glycosylphosphatidylinositol) anchor of a group of surface proteins on circulating cells. Laboratory findings in PNH include typical findings of hemolytic anemia, loss of GPI-anchored proteins. brown ford c max
