On this page
Factor V Leiden thrombophilia is caused by a specific mutation in the Factor V gene. Factor V plays a critical role in the formation of blood clots in response to injury. Genes are our body’s instructions for making proteins. The factor V gene instructs the body how to make a protein called coagulation factor V. Coagulation factor V is involved in a series of chemical reactions that hold blood clots together. A molecule called activated protein C (APC) prevents blood clots from growing too large by inactivating factor V.
