A Czechoslovakian teenager with Hb E-β∘-thalassemia [IVS-I-1 (G → A)] complicated by the presence of an α-globin gene triplication

  • 32 Accesses

We have examined the molecular basis of three inherited hemoglobin (Hb) disorders present in a Czechoslovakian girl with a severe, transfusion-dependent, hemolytic anemia. She is heterozygous for Hb E (on a genetic background specific for Czechoslovakian families), heterozygous for the β∘-thalassemia (thal) allele IVS-I-1 (G → A), and heterozygous for an α-globin gene triplication. The combination of these three undesirable traits results in a severe chain imbalance that is the basis of the serious hemolytic disorder observed in this teenager.
