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)|
