Acquired hemophilia can occur in association with other underlying conditions that involve the immune system, like cancer, other autoimmune diseases, pregnancy or even the use of certain medications (shown in pie chart below).
The protein involved with hemophilia A is factor VIII (factor 8) and with hemophilia B is factor IX (factor 9). Picture of the blood clotting process. Hemophilia A is caused by a mutation in the gene for factor VIII, so there is deficiency of this clotting factor. Hemophilia B (also called Christmas disease) results from a deficiency of factor IX due to a mutation in the corresponding gene. A condition referred to as hemophilia C involves a deficiency of clotting factor XI. This condition is much rarer than hemophilia A and B and typically leads to mild symptoms. It is also not inherited in an X-linked manner and affects persons of both sexes.
