Özet

Alpha thalassemia (alpha-thal) is one of the most common genetic disorders in the world. It is characterized by the absence or reduced expression of alpha-globin genes. The frequency of alpha-thal mutations in the province of Hatay in South Turkey is unknown. Therefore, in the present study, we aimed to investigate the spectrum of alpha-thal mutations in this province. Three hundred and nine patients were tested for alpha-thal mutations by using reverse dot blot hybridization technique and nine different mutations were detected in 97 of them. Among the 9 different mutations found, the most frequent mutations were the -alpha(3.7) (43.81%), -alpha 2(-5nt) (6.70%), - -(MED) (5.67%) and alpha 2(Poly) (A2) (2.57%). In the present study, - -(FIL) mutation was detected in a patient for the first time in Turkey. Our results indicated that alpha-thal mutations are highly heterogeneous and -alpha(3.7) is the most prevalent mutation in Hatay province of South Turkey. In addition, - -(FIL) mutation was detected in a patient for the first time in Turkey. This new finding may contribute to the establishment of a national mutation database and genetic counseling.
