Introduction: Beta-thalassemia is an autosomal recessive disease that occurs as a result of a disorder in the (β-globin chains synthesis), and the gold standard method for diagnosis is genetic mutation analysis. It is important to know the distribution of mutations according to regions and races. The aim of this study is to document the mutations in the beta-globin gene of beta-thalassemia major and intermedia patients who were followed and treated in Sanliurfa province, and to examine the relationships between these mutations by defining them according to gender, nationality, consanguineous marriage, history of disease in siblings and blood type.

Methods: The files of 272 patients diagnosed with beta-thalassemia major and intermedia followed up in the Pediatric Hematology-Oncology outpatient clinic of Sanliurfa Training and Research Hospital between August 2016 and August 2017 were retrospectively reviewed and mutation analyzes were documented. Coding exons and exon-intron junction regions of beta globin-HBB gene were amplified by PCR method and then DNA sequencing was performed. Gender, nationality, consanguineous marriage, sibling history and blood type information were recorded.

Results: Out of 272 patients, 94.1% were thalassemia major and the others were thalassemia intermedia. Approximately one third of the patients (30.1%) were foreign nationals. A total of 27 different mutations in the beta-globin gene were detected. The most common mutation is IVS-I-110 c.93-21 (G> A) (23.1%), which is followed by IVS-I-1 c.92 + 1 (G> A) (15.8%) and Codon 39 c.118 (C> T) (11.5%). One hundred and forty-two individuals (52.2%) had no sibling history, while 103 (37.9%) had one sibling and 27 (9.9%) had two siblings with thalassemia disorder. First-degree, second degree and third degree consanguineous marriages were present in 42.6% (n = 116), 8.1% (n = 22), 11% (n = 30) of parents, respectively.

Conclusions: Beta-thalassemia disease is a common hematological condition in Sanliurfa. Approximately one-third of the patients who apply are foreign nationals. Correct identification of beta-globin gene mutations will guide genetic counseling and preventing prenatal disease. This data can contribute to the national thalassemia prevention program in Turkey.

Giriş: Beta-talasemi, β-globin zincir sentezindeki bir bozukluk sonucu ortaya çıkan otozomal resesif geçişli bir hastalık olup, tanı koyabilmek için altın standart yöntem genetik mutasyon analizidir. Bölgelere ve ırklara göre mutasyon dağılımlarının bilinmesi önem taşımaktadır. Bu araştırmanın amacı, Şanlıurfa ilinde takip ve tedavi edilen beta-talasemi majör ve intermedia hastalarının beta-globin geninde bulunan mutasyonları dökümante etmek ve bu mutasyonların cinsiyet, uyruk, akraba evliliği, kardeşte hastalık öyküsü ve kan grubuna göre tanımlamasını yaparak aradaki ilişkileri incelemektir.

Yöntem: Şanlıurfa Eğitim ve Araştırma Hastanesi Çocuk Hematoloji-Onkoloji polikliniğinde Ağustos 2016-Ağustos 2017 takip edilen beta-talasemi majör ve intermedia tanılı 272 hastanın dosyaları retrospektif olarak taranarak mutasyon analizleri dökümante edildi. Mutasyon analizleri, Beta globin-HBB geninin kodlama yapan ekzonları ve ekzon-intron bağlantı bölgeleri PCR yöntemi ile amplifiye edildikten sonra DNA dizi analizi ile yapıldı. Cinsiyet, uyruk, akraba evliliği, kardeş öyküsü ve kan grubu bilgileri kaydedildi.

Bulgular: İki yüz yetmiş iki hastanın %94,1’ini talasemi majör, diğerlerini talasemi intermedia olguları oluşturmaktaydı. Hastaların yaklaşık üçte biri (%30,1) yabancı uyrukluydu. Beta-globin geninde toplam 27 farklı mutasyon saptandı. En sık görülen mutasyon IVS-I-110 c.93-21 (G>A) (%23,1) olup, bunu IVS-I-1 c.92+1 (G>A)‎ (%15,8) ve Codon 39 c.118 (C>T) (%11,5) takip etmekteydi. Yüz kırk iki kişide (%52,2) kardeş öyküsü bulunmazken 103 kişide (%37,9) bir kardeşte, 27 kişide ise ‎‎(%9,9) iki kardeşte hastalık bulunmaktaydı. Hastaların anne ve babalarının %42,6’sında ‎‎(n=116) birinci derece, %8,1’inde (n=22) ikinci derece, %11’inde (n=30) ise ‎üçüncü derece akraba evliliği söz konusu idi.‎

Sonuç: Şanlıurfa’da beta-talasemi hastalığı, sık görülen bir hematolojik durumdur. Başvuran hastaların yaklaşık üçte biri yabancı uyrukludur. Beta-globin gen mutasyonlarının doğru tanımlanması genetik danışma ve doğum öncesi hastalığın engellenebilmesi açısından yol gösterici olacaktır. Bu veriler, Türkiye’de ulusal talasemi önleme programına katkı sağlayabilir.
