Molecular Characterization of the Factor IX Gene in 28 Iranian Hemophilia B Patients
Journal Title: Iranian Journal of Blood and Cancer - Year 2009, Vol 1, Issue 2
Abstract
Background: Heterogeneous mutations in the human coagulation factor IX gene lead to an X-linked recessive bleeding disorder known as hemophilia B. The disease is distributed worldwide with no ethnic or geographical priority. Materials and Methods: The aim of this study was to characterize the factor IX gene mutations in 28 unrelated Iranian hemophilia B patients. Polymerase chain reaction (PCR) and direct sequencing was performed for all functionally important regions of the gene. Haplotype analysis was performed using three markers. Results: We identified 24 point mutations and four small deletions (one novel mutation). Overall, 20 different mutations were found and patients with common mutations had identical haplotype. Conclusion: These data confirm high molecular heterogeneity of the mutations causing hemophilia B and will enable carrier testing and prenatal diagnosis for family members.
