Welcome to the IHTC’s Clotting Disorders webpage. This section provides information on various issues related to clotting disorders that will help you make informed decisions about your care.

How Do I Find the Information I Need?

If you need information on a specific condition, click on the appropriate condition in Table 1 (Inherited Causes) or the list below (Acquired Causes).

Inherited Causes of Blood Clots

Table 1. Inherited Causes of Blood Clots
Increased Levels of Procoagulants Decreased Levels of Anticoagulants Abnormal Fibrinolysis Other Inherited Causes
Factor V Leiden mutation or activated protein C resistance* Antithrombin Plasminogen Deficiency Paroxysmal Nocturnal Hemoglobinemia
Prothrombin 20210 mutation Protein C Decreased Levels of Tissue Plasminogen Activator (t-PA)
Hyperhomocysteinemia Protein S Increased Levels of Plasminogen Activator Inhibitor-1 (PAI-1)
FVIII, FIX, FXI, FVII, VWF Thrombomodulin Elevated Thrombin-Activatable Fibrinolysis Inhibitor (TAFI)
