An extra X does not prevent acquired hemophilia

The journal Thrombosis Research has published an article about acquired hemophilia. Acquired hemophilia A (AHA) is a severe bleeding disorder caused by autoantibodies against clotting factor VIII (FVIII). With an estimated annual incidence of 1.3 to 1.5 per million, AHA is a rare disease. An extremely rare form of AHA has been described among women in the peripartum period, and may present with peripartum hemorrhage. The full-text article you can find here.
