摘要

Ninety-eight postnatal and six prenatal cases?of thalassemia?were studied?by the reverse dot-blot hybridization technique?in the city of Gaziantep, Turkey. We found the following mutations:?IVS 1.110 (G>A) in 29.1%, IVS 2.1 (G>A) in 12.3%, IVS 1.1 (G>A) in 7.7%, Codon 8 (?AA) in 5.6%,?-30 (T>A) in 4.6%, IVS 1.6 (T>C) in 4.6%,Codon 39 (C>T) in 3.6%, Codon 44 (-C) in 3.1%, IVS 2.745 (C>G) in 1.5%, Codon 8/9 (+G) in 2.1%, Codon 36/37 (-T) in 2.1%, IVS 1.5 (G>C) in 2.1%, Codon 22 (7pb del)?in 0.5%,?Codon 5 (-CT)?in 0.5% while 20.9% were undetermined. 54 of the thalassemia patients were homozygotes, 12 were compound heterozygous and 31 were heterozygotes. In one allele of 5 thalassemia patients, α-thalassemia mutation (3.7 single gene deletions in 1 patient, anti-3.7 gene triplication in 4 patients) was determined at the same time. Finally, this is the first comprehensive study in this region and percentage of α and β- globin genes mutation is 2.6 and 79.4%, respectively.
