ABSTRACT
Beta-thalassemia, an autosomal recessive disease, results from mutations of the beta-globin gene. More than 40 different mutations found in Turkish beta-thalassemia patients are mostly composed of point mutations, and only in very rare cases a deletion or an insertion causes beta-thalassemia phenotypes. Here, we report two patients who were clinically diagnosed with beta-thalassemia major and HbS/beta-thalassemia respectively. We performed reverse dot blot hybridization method and automated sequence analysis to detect the mutations. One of the patients was found to be IVS I.130 (G-C) homozygous, the other was HbS/IVS II.848 (C-A) as compound heterozygous. The aim of this study was to report hematological and clinical findings in both cases related with beta-globin gene defects that are very rare.
