Persistence of fetal hemoglobin

Mediterranean, a-thalassemia and hemoglobin C in Africa, and hereditary persistence of fetal hemoglobin in North Africa and India. These combinations have created diverse presentations of this disease, the most severe being hemoglobin SS and hemoglobin S(3 zero thalassemia. 

Patients who have hemoglobin SS as well as a mutation that produces hereditary persistence of fetal hemoglobin have few...
