Abstract This study was carried out on Clinical Patholgy and Pediatric artments, Zagazig University Hospital. The aim of this study was to detect different gene mutations mg B-thalassaemia trait individuals by PCR and to determine role of PCR in the diagnosis of silent carriers. It included 40 jects classified into 2 groups: Group I : Included 20 hetrozygous B-thalassaemia carriers, .cted from parents of children with B-thalassaemia major. Group II : Included 20 apparently healthy subjects, served as trol group. !All members of the study were subjected to the following estigations History taking and complete clinical examination. Routine investigations including: CBC, reticulocytic count, Hb electrophoresis and estimation of serum iron & serum bilirubin. Special investigations including: OPOF, HBA2 quantitation by hromatography and qualitative detection of B-thalassaemia utations by using PCR-based allele specific oligonucleotides. Statistical analysis was done and came to the following : - No ’significant difference in serum bilirubin & serum iron and between the carrier and control groups. |
