Carrier detection of Hemophilia B by using a restriction site polymorphism associated with the coagulation Factor IX gene.
The cloned complementary DNA for coagulation Factor IX (FIX) detects a frequent restriction fragment length polymorphism (RFLP) in human genomic DNAs digested with the restriction endonuclease Taq I. This genetic marker was used, in parallel with coagulation and immunological assays, to follow the segregation of an abnormal FIX gene in a large Hemophilia B family. Among the six potential female...
متن کاملIntragenic Factor IX restriction site polymorphism in hemophilia B variants.
This study includes 47 normal subjects and 25 hemophilia B patients without inhibitor(s), showing different factor IX coagulant activity and antigen levels. Genomic DNA, digested with various restriction endonucleases, was hybridized with two different factor IX probes, ie, the cDNA and the subgenomic probe for the intragenic TaqI polymorphic site. cDNA restriction patterns suggest absence of g...
متن کاملCoagulation Factor IX for Hemophilia B Therapy
Factor IX is a zymogen enzyme of the blood coagulation cascade. Inherited absence or deficit of the IX functional factor causes bleeding disorder hemophilia B, which requires constant protein replacement therapy. Reviewed herein are the current state in the manufacturing of FIX, improved variants of the recombinant protein for therapy, transgenic organisms for obtaining FIX, and the advances in...
متن کاملThe Frequencies of three Factor IX-Linked Restriction Fragment Length Polymorphisms in Iranian Patients with Hemophilia B
Background: Hemophilia B is an X-linked recessive coagulation disorder caused by factor IX deficiency. Analysis of factor IX gene polymorphisms is considered the best approach for prenatal diagnosis and carrier detection of hemophilia B where the identification of gene mutation is not easily possible. Objective: To study the frequency of three factor IX-linked restriction fragment length polym...
متن کاملMolecular Characterization of the Factor IX Gene in 28 Iranian Hemophilia B Patients
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)...
