These findings suggest that the bone marrow characteristics in GATA-1 DBA-like patients are distinct from the typical bone marrow findings in DBA with RP gene variants, characterized by a quantitative intrinsic erythroid defect or erythroblastopenia (absence or less than 5% of erythroblasts in otherwise normocellular bone marrow with no signs of dysplasia). The gene discussed is GATA1; the disease is Erythroid hypoplasia.
