mutations in the PROC gene and inherited in an autosomal dominant fashion.Protein C deficiency is a disorder of blood clotting. People with this condition have an increased risk of developing abnormal blood clots. Protein C is found in the bloodstream and blocks the activity of (inactivates) certain proteins that promote blood clotting. Those with protein C deficiency do not have enough functional protein C to inactivate clotting proteins, which results in an increased risk of developing abnormal blood clots. Other factors can raise the risk of abnormal blood clots in people with mild protein C deficiency. These factors include increasing age, surgery, immobility, or pregnancy. The combination of protein C deficiency and other inherited disorders of blood clotting can also influence the risk. However, most people with mild protein C deficiency never develop abnormal blood clots. Protein C deficiency can be inherited or acquired. Inherited forms are caused by
