what causes v111 deficiency haemophilia
Combined factor V and factor VIII deficiency is an inherited bleeding disorder that is caused by low levels of factors V and VIII.

The combination of factor V and factor VIII deficiency does not seem to cause more bleeding than if only one or the other of the factors were affected. The symptoms of combined factor V and factor VIII deficiency are generally mild. See Bleeding Symptoms of Rare Clotting Factor Deficiencies.
