Why are hemoglobin F levels increased in HbE/beta thalassemia?
To try to further define the mechanisms that increase the levels of hemoglobin F (HbF) in the blood of patients with severe forms of beta thalassemia, we have studied two comparable populations of hemoglobin E (HbE)/beta thalassemics, one regularly transfused and one receiving only occasional blood transfusions. Regular transfusion was associated with a significant decrease in soluble transferr...

متن کاملHemoglobin E-beta thalassemia: factors affecting phenotype.
The phenotype of E-beta-thalassemia is affected by several genetic factors. The aim of this study was to analyze severity of E-beta-thalassemia and correlate with HbE, HbF, E/F ratios, beta-mutation and Xmn I polymorphism. Thirty cases of E-beta-thalassemia (23 with childhood onset) were studied. HbE levels were quantitated by HPLC. Xmn1 polymorphism and beta-mutations were studied by PCR-RFLP ...
متن کاملCorrelation of BACH1 and Hemoglobin E/Beta-Thalassemia Globin Expression
OBJECTIVE The diverse clinical phenotype of hemoglobin E (HbE)/β-thalassemia has not only confounded clinicians in matters of patient management but has also led scientists to investigate the complex mechanisms involved in maintaining the delicate red cell environment where, even with apparent similarities of α- and β-globin genotypes, the phenotype tells a different story. The BTB and CNC homo...
