Thrombophilia, an increased tendency to form abnormal blood clots that can obstruct blood vessels, is caused by an inherited disorder of blood clotting known as Factor V Leiden thrombophilia. This disorder is characterized by a specific gene mutation called Factor V Leiden.
Individuals with factor V Leiden thrombophilia are at a heightened risk of developing deep venous thrombosis (DVT), a type of blood clot that commonly occurs in the legs but can also affect other areas such as the brain, eyes, liver, and kidneys. Additionally, this condition increases the likelihood of clots breaking away from their original location and traveling through the bloodstream, potentially leading to pulmonary emboli in the lungs. However, it is important to note that only a small percentage (around 10%) of those with the factor V Leiden mutation will experience abnormal clotting.
Factor V Leiden can affect both genders. However, women who possess the mutation may experience a higher likelihood of developing blood clots while pregnant or using estrogen hormone therapy.
Factor V Leiden thrombophilia is caused by a specific mutation in the F5 gene, which is responsible for producing coagulation factor V. This protein is essential in the coagulation system, a sequence of chemical reactions that results in the formation of blood clots following an injury.
Several proteins, including activated protein C (APC), regulate the coagulation system. APC's role is to deactivate coagulation factor V, which slows down clotting and prevents excessive clot growth. However, individuals with factor V Leiden thrombophilia cannot have their coagulation factor V inactivated by APC as it normally would. This leads to a prolonged activation of the clotting process, increasing the likelihood of abnormal blood clot formation.
