Abstract

Objective: Hemophilia B is caused by coagulation defects in the factor IX gene located in Xq27.1 on the X chromosome. A wide range of mutations, showing extensive molecular heterogeneity, have been described in hemophilia B patients. Our study was aimed at genetic analysis and prenatal diagnosis of hemophilia B in order to further elucidate the pathogenesis of the hemophilia B pedigree in China.Materials and Methods:Polymerase chain reaction amplification and direct sequencing of all the coding regions was conducted in hemophilia B patients and carriers. Prenatal diagnosis of the proband was conducted at 20 weeks.Results:We identified the novel point mutation 10.389 A>G, located upstream of the intron 3 acceptor site in hemophilia B patients. The fetus of the proband's cousin was identified as a carrier.Conclusion:Our identification of a novel mutation in the F9 gene associated with hemophilia B provides novel insight into the pathogenesis of this genetically inherited disorder and also represents the basis of prenatal diagnosis

Özet

Amaç: Hemofili B, X kromozomu üzerinde Xq27,1'e lokalize faktör IX genindeki koagülasyon defektleri nedeniyle oluşur. Hemofili B hastalarında yaygın moleküler heterojenite gösteren ve geniş bir dağılımı olan mutasyonlar tanımlanmıştır. Çalışmamız Çin'deki bir hemofili B ailesindeki patogenezi açığa kavuşturulmak için hemofili B'nin genetik analizi ve prenatal tanısını amaçlamıştır Gereç ve Yöntemler:Hemofili B hastalarında ve taşıyıcılarda tüm kodlanan bölgelerin polimeraz zincir reaksiyonu ile amplifikasyonu ve direkt dizileme yapılmıştır. Probandın prenatal tanısı 20. haftada yapılmıştır. Bulgular: Hemofili B hastalarında yeni bir nokta mutasyonu olan 10,389 A>G'nin intron 3'ün alıcı bölgesinin yukarı akımında bulunduğunu tanımladık. Probanın kuzeninin cenininin de taşıyıcı olduğu bulundu. Sonuç:F9 geninde hemofili B ile ilişkili yeni bir mutasyonu tanımlamamız genetik olarak kalıtılan bu hastalığın patogenezine yeni bir açıklama getirmiştir ve prenatal tanının temelini temsil etmektedir.
