About Hemophilia
Normal paragraph

For more information about haemophilia, please visit the European Haemophilia Consortium (EHC) website.

*The EHC represents 48 national patients’ organisations for people with rare bleeding disorders from 27 Member States of the European Union (EU) and most Member States of the Council of Europe. The organisation is not affiliated with the Portraits of Progress campaign.


Haemophilia is a rare disorder in which blood doesn’t clot in the typical way because it doesn’t have enough blood-clotting proteins (clotting factors).7

The two most common types of haemophilia are A and B.7 

Haemophilia A is the most common type of haemophilia and is caused by a lack of blood clotting factor VIII (FVIII), whereas haemophilia B is caused by a lack of factor IX (FIX).7

The more severe the condition, the less able a person is to form blood clots, making them more vulnerable to bleeding.5
