Thrombophilia is a disorder characterized by an increased tendency to form abnormal blood clots due to genetic or acquired factors affecting the coagulation system. It is clinically significant as it raises the risk of venous thromboembolism, which can lead to complications such as deep vein thrombosis or pulmonary embolism. One key association is with inherited conditions like Factor V Leiden mutation, which predisposes individuals to recurrent thrombotic events.
