Abstract Objectives This study, detection of beta globin gene mutations in thalassemia major patients who migrated from Syria to Kahramanmaraş region were planned. Materials and methods The study included 35 Syrian national beta thalassemia major patients. Beta globin gene mutations were detected by ARMS (Amplification Refractory Mutation System) method, RFLP (Restriction Fragment Length Polymorphism) method and DNA sequence analysis. Codon 15, codon 9/10, codon 5 and codon 8 mutations, which we could not detect with other methods in our study, were detected by sequence analysis. Results In beta thalassemia major patients, 16 types of mutations were detected, the most common being IVS-I-110 (n=8). Other mutations are according to frequency order IVS-II-745 (n=3), codon 44 (n=3), codon 15 (n=3), IVS-I-110/IVS-I-1 (n=3), codon 5 (n=2), IVS-I-1 (n=2), codon 8/IVS-II-1 (n=2), codon 44/codon 15 (n=2), IVS-II-1 (n=1), codon 39 (n=1), IVS-I-6/codon 5 (n=1), codon 9/10 (n=1), IVS-I-110/codon 39 (n=1), IVS-I-5/IVS-II-1 (n=1), codon 39/IVS-II-745 (n=1). Conclusions According to the results of our study beta-thalassemia mutations in Syrian immigrant groups show heterogeneity and mutation types of mutation map is similar to Turkey. The conclusion is to prevent families to have a second patient child by genetic counseling.

This study was planned to determine the frequency of β-thalassemia mutations in Batna region (Northeast Algeria). Nineteen blood samples of clinically thalassemic children patients were collected from Department of Pediatrics, University Hospital of Batna. We carried out the molecular genetics of beta globin gene by the method of minisequencing using Snapshot™ kit (Applied Biosystems) in search of the four most common HBB genetic variants including three β-thalassemia mutations: codon 39(C&gt;T) (<em>HBB</em>: c.118C&gt;T), IVSI-110(G&gt;A) (<em>HBB</em>: c.93-21G&gt;A), and IVSI-1-2(T&gt;G) (<em>HBB</em>: c.92+2T&gt;G), as well as the hemoglobin S variant (<em>HBB</em>: c.20A&gt;T). We used direct DNA sequencing to detect the rare mutations of beta-globin gene. We have revealed the presence of four different <em>β</em>-globin gene mutations responsible for <em>β</em>-thalassemia in Batna region. According to our results, the nonsense mutation at codon 39 (C&gt;T) is the most frequent mutation type in our province, the same as other geographical regions of Algeria. It is followed by codon 54(-T), detected in a second Algerian family (the proband was homozygote), and the first association of Hb Knossos: codon 27 (G&gt;T) allele with codon 39 (C&gt;T) in the Algerian population. Here we reportws also the association of codon 39(C&gt;T) with IVS-I-110 (G&gt;A). Our preliminary results show the predominance of codon 39 (c&gt;t) mutation of <em>HBB</em> gene in Batna region.
