Beta globin mutations in beta thalassemia minor patients in Genetics Diagnosis Center of Trakya University Faculty of Medicine

Abstract

Aim: Beta thalassemia is an autosomal recessive genetic disorder caused by more than four hundred mutations in the beta globin (HBB-Hemoglobin Beta Locus) gene. 236 patients referred to our Genetic Disorders Diagnosis Center with beta thalassemia minor clinic to determine the frequency of HBB gene mutations in the Thrace Region. Materials and Methods: Beta globin genetic analysis was performed by sanger sequence from peripheral blood samples obtained from all included cases. Results: 98 heterozygous HBB gene mutations were detected in 97 (41.1%) patients. HBB gene mutations were IVS I.110 (G>A) (28.6%), Codon 39 (C>T) (18.4%), IVS1-1G>A, c.92+1 (G>A) (8.2%), IVS II.745 (C>G) (7.1%), IVS I.6 (T>C) (5.1%), Codon 8 (-AA), c.25.26.delAA (4.1%), Codon 44 (-C) (4.1%), Hb F Carlton (3.1%), Cd 5 [-CT], c.17.18delCT (3.1%), cd8/9+G, c.27_28insG, c.27dupG (3.1%), c.364 G>A, p.Glu122Lys (3.1%), c.-31 C>T (3.1%), CD6 –A, c.20delA (3.1%), c.*+111A>G (PolyA) (A>G) (2%), IVS-II-1 (G>A), c.315+1 G>A (1%), c.30.31insT, p.Ala11Cysfs (1%), CD26 G>A (Hb E), c.79 G>A (1%), CD15 G>A, c.48 G>A (1%). In our study, we found eighteen different HBB gene mutations in the Thrace region. Conclusion: Our results are presenting that beta thalassemia trait is not frequent only in Aegean, Mediterranean and Southeast Anatolia region in Turkey geography, but also frequent in the Thrace region to the literature.
