MOLECULAR ANALYSIS OF NON-TRANSFUSION DEPENDENT THALASSEMIA ASSOCIATED WITH HEMOGLOBIN E-β-THALASSEMIA DISEASE WITHOUT α--THALASSEMIA

Background The finding of many Thai Hb E-β0-thalassemia patients with non-transfusion dependent thalassemia (NTDT) phenotype without co-inheritance of α-thalassemia has prompted us to investigate the existence of other genetic modifying factors.
