SCD = sickle cell disease; MAP = microangiopathic hemolytic anemia; AHA = autoimmune hemolytic anemia; HA = hemolytic anemia in a lymphoma patient after chemotherapy; SA = sideroblastic anemia (the 9-year-old is an idiopathic sideroblastic sex-linked anemia, the 26-year-old is a variant of myelodysplastic syndrome).
