Abstract

Background: Approximately 180 MUTATIONS have been described in Β-THALASSEMIA worldwide with specific spectrum in each ethnic population. This study determines the spectrum and the frequency of Β-THALASSEMIA MUTATIONS in patients with Β-THALASSEMIA trait and SICKLE CELL-Β-THALASSEMIA.Methods: Fifteen compound heterozygous SICKLE CELL thalassemia (SCT) and 23 Β-THALASSEMIA trait patients were studied using reverse dot blot, denaturing gradient gel electrophoresis and direct genomic sequencing.Results: We detected distinct Β-THALASSEMIA alleles in 15 compound heterozygous of SCT and 23 Β-THALASSEMIA trait patients. The most common mutation was IVSII-1(G→A), found in 15 of the 38 thalassemia chromosomes. IVSII.1 (G→A) mutation is a single nucleotide change of G to A at intervening sequence 2 position 1 of β-globin gene, detected in 11 out of 23 chromosomes in A/β-thalassemic patients and in four out of 15 chromosomes of SCT patients. This mutation constituted about 39% of the MUTATIONS in both groups. The -25bp 3 IVSI, deletion of 25 base pairs from 3' end of intervening sequence 1 of β-globin gene, was found to be the second prevalent mutation among all chromosomes.Conclusion: Defining thalassemia MUTATIONS are necessary to establish prenatal diagnosis programs leading to lower medical cost. Amongst 10 different types of mutation detected in β- thalassemic patients from South of IRAN, two MUTATIONS of IVSII-1(G→A) and -25bp 3' IVSI were the most predominant β-thalassemic alleles.
