Biology of inherited coagulopathies: factor IX
Abstract
Characterization of the functional domains of FIX and related vitamin K-dependent proteins has been enhanced by the isolation and characterization of the genes encoding these proteins. A better understanding of the interactions between FIX's activators, cofactors, and substrate, FX, has been gained through the study of naturally occurring variants isolated from patients with hemophilia B and genetically engineered recombinant molecules. With the determination of specific mutations in hemophilia B kindreds, and through advances in molecular techniques, especially the polymerase chain reaction, more accurate determination of carrier status and prenatal diagnosis can now be made.
