Gene Information from Publications

Publication Link Summary of findings
17823237 In patients with paroxysmal nocturnal hemoglobinuria, it is very unlikely that more than one PIG-A mutated clone arises at the level of the hematopoietic stem cells.
12130519 Decreased susceptibility of leukemic cells with PIG-A mutation to natural killer cells in vitro allows paroxysmal nocturnal hemoglobinuria clones to escape immune attack.
12037021 Molecular testing for mutations in the PIG-A gene can serve as a confirmation test of paroxysmal nocturnal hemoglobinuria.
12411324 PIG-A gene abnormality in precursor cells and changes of expression of GPI-anchored protein and contribution of paroxysmal nocturnal hemoglobinuria clones with PIG-A gene abnormalities among various cell lineages during differentiation and maturation
15687243 PIG-A mutations are relatively common in normal hematopoiesis
16923549 review of the clinical and biological relevance of PIG-A mutations in paroxysmal nocturnal hemoglobinuria, aplastic anemia and healthy controls [review]
12424196 The spectrum of PIG-A gene mutations in aplastic anemia/paroxysmal nocturnal hemoglobinuria reveals a high incidence of multiple mutations and evidence of a mutational hot spot.
