[Research Progress on Genetic Factors and Hemophilia A Clotting Factor Inhibitor-Review]

Hemophilia A (Hemophilia A, HA) is an X-linked recessive hereditary coagulation function disorder, the deficiency and dysfunction of blood coagulation were caused by the mutations of gene encoding clotting factor VIII. The treatment of hemophilia A still depends on the replacement therapy with blood coagulation factor. However, the repeated infusion of clotting factor will produce the neutralizing antibody against FVIII, then resulting in one of the serious complications. The reports on the incidence of inhibitor are different at home and abroad. Due to diverse factors, the inhibitors of hemophilia A clotting factor mainly can be divided into genetic and environmental factors, In this review, the inhibitors of hemophilia A clotting factor and their risk factors are briefly summarized.
