What are the types of inherited thrombophilia?
You may have a life-long risk for having a clot event if you were born with one or more of these conditions: • Absent or low levels of antithrombin: Antithrombin is a substance that stops the action of thrombin. Thrombin is an enzyme (special protein) that starts the formation of a clot. When antithrombin is absent or decreased, clot formation increases. • Absent or low levels of blood proteins: Proteins C and S are found in the blood and work to control the clotting process. When one of these proteins is not present in the blood or when levels are decreased, too much clotting can occur. • Gene defect: A gene is a little piece of information that tells the body what to do or what to make. Problems or defect with the blood genes, such as factor V (five) Leiden or factor II (two), may increase clot formation. • High levels of clotting factors: There are many types of clotting factors needed in the clotting process, including factors VIII (eight), IX (nine), and XI (eleven).
