Protein S Deficiency (PSD) is a rare blood disorder that affects just a few thousand people worldwide. It is one of several known risk factors for thrombophilia and can increase the risk of blood clots such as Deep Vein Thrombosis (DVT) and Pulmonary Embolism (PE).

Information about thrombophilia is widely available on the Internet but it tends to focus on the more common risk factors such as Factor V Leiden, Antithrombin III Deficiency or Protein C Deficiency. If there is any specific mention of Protein S Deficiency it is likely to be brief, because after all, PSD is a rare condition.

This website's aim is to complement the other information sources by focusing on details specific to PSD and to improve understanding and awareness of Protein S Deficiency.
