Abstract
β thalassemias are usually transmitted as autosomal recessive traits. However, some dominant forms of β thalassemia have been identified in individuals who have inherited a single copy of an abnormal β globin gene. Thalassemia intermedia with mild anemia, jaundice, and splenomegaly has been observed in these patients. Electrophoresis has shown elevated Hemoglobin(Hb) A2 and Hb F levels. In particular, there are inclusion bodies in the erythroid precursors and peripheral red blood cells after splenectomy. The molecular basis of these dominant β thalassemias is heterogeneous. The authors studied the first Korean case of dominantly inherited β thalassemia due to Hb Dieppe. Hb Dieppe is a missense mutation of β codon 127(CAG→CGG)Gln→Arg. The patient in this case was characterized by moderate anemia, hypochromia, microcytosis, elevated Hb A2 levels, elevated Hb F levels and splenomegaly. The father of the patient also has the same disease. We report this case and review related literature.
Key Words: Dominantly inherited β thalassemia, Hb Dieppe
