Changes in the F8 gene are responsible for hemophilia A, while mutations in the F9 gene cause hemophilia B.

Silver chart price A related protein, coagulation factor IX, is produced from the F9 gene. Australian dollar trend 2016 Coagulation factors are proteins that work together in the blood clotting process . Stock market futures bloomberg After an injury, blood clots protect the body by sealing off damaged blood vessels and preventing excessive blood loss.

Mutations in the F8 or F9 gene lead to the production of an abnormal version of coagulation factor VIII or coagulation factor IX, or reduce the amount of one of these proteins.
