Haemophilia C
(重定向自Hemophilia C)
Haemophilia C (also known as plasma thromboplastin antecedent (PTA) deficiency or Rosenthal syndrome) is a mild form of haemophilia affecting both sexes. However, it predominantly occurs in Jews of Ashkenazi descent. It is the fourth most common coagulation disorder after von Willebrand's disease and haemophilia A and B. In the USA it is thought to affect 1 in 100,000 of the adult population, making it 10% as common as haemophilia A.
