Abstract
Alpha thalassemia is a genetic disease characterized by insufficient expression or definite absence of the α-globin chain. Three large deletions (thal-1; 26.5 kb or MedII, 20.5 kb and 17.4 kb or MedI) and two small deletions (thal-2; 4.2 kb and 3.7 kb) have been characterized in our country. In addition, two different PolyA mutations (PA1: AATAAA>AATAAG and PA2: AATAAA>AATGA) on the α2-globin gene (αα/αPAα), 5nt deletion (αα/α5ntα), and unstable Hb variant (CD 59; GGC→GAC) synthesized by the α1-globin gene (αα/ααCD59) have been reported. More than ten different combinations of α-thal-1 and α-thal-2 (--/-α) or HbH genotypes with point mutations (--/αPAα or --/ααCD59) were determined. In this study, which was carried out in Çukurova region, it is aimed to emphasize the importance of giving genetic counseling to families with alpha thalassemia carriers and to determine genotype combinations. DNA was isolated from blood samples taken from 5 children and their families who were admitted to Çukurova University Balcalı Hospital and diagnosed with severe anemia (Hb
