In brief: Hemophilias
Hemophilia is a bleeding disorder, usually inherited with an x-linked recessive inheritance pattern, which results from the deficiency of a coagulation factor. Hemophilia a results from the deficiency of clotting factor viii.
Hemophilia b results from the deficiency of clotting factor ix. Acquired hemophilia is a separate noninherited condition, rarer than congenital hemophilia, autoimmune.
