Abstract
Somatic mutation in the PIG-A gene is the initial event in the pathogenesis of paroxysmal nocturnal hemoglobinuria (PNH), but the pathophysiologic mechanisms leading to clonal expansion remain unclear. The intricate association of PNH with immune-mediated bone marrow failure syndromes, including aplastic anemia (AA), suggests an immunologic selection process for the glycosylphosphatidyl-inositol (GPI)-deficient hematopoietic clone. The mechanism for the growth advantage of PNH cells may be related to the nature of the antigens targeted by the immune response or to the function of immunomodulatory GPI-anchored proteins on the surface of the hematopoietic target cells. Alternative theories of PNH evolution may include intrinsic properties of the mutated cells, but the experimental evidence is largely lacking. Elucidation of the pathogenesis of PNH may provide key information about the causes of idiopathic AA and help understand the regulation of the hematopoietic stem cell compartment.
