Alpha-Thalassemia in Tunis-about 3 cases of hemoglobin H.

ABSTRACT

The authors report results about three cases of hemoglobinose H descended from the same town in the North East region of Tunisia and being not in way related. Molecular lesions analysis of this type of alpha thalassemia are polymorphic, explaining heterogenity of clinical disorders. The three patients described in this study occurred with a relatively severe symptomatology suspecting not only deletion type defects at the alpha genome level but possible existence of non deletional type defect of alpha 2 gene
