What is Factor V Leiden?
The most common inherited thrombophilia, caused by a specific point mutation in the gene encoding factor V (the G1691A or Arg506Gln mutation) that makes factor V resistant to inactivation by activated protein C, leading to prolonged clot-promoting activity. It is present in approximately 5% of European-ancestry individuals and increases the lifetime risk of venous thromboembolism, particularly in combination with other risk factors.
