Factor V Leiden thrombophilia is an inherited disorder of blood clotting.
Factor V Leiden is the name of a specific mutation (genetic alteration) that results in thrombophilia, or an increased tendency to form abnormal blood clots in blood vessels.
People who have the factor V Leiden mutation are at somewhat higher than average risk for a type of clot that forms in large veins in the legs (deep venous thrombosis, or DVT) or a clot that travels through the bloodstream and lodges in the lungs (pulmonary embolism, or PE).

However, the thrombophilias contribute to a number of pregnancy complications, including fetal losses that occur in late in the first trimester or in the second or third trimesters (i.e., stillbirths), placental abruption (when the placenta separates from the uterine wall, partially or completely, before delivery) and poor fetal growth.
The thrombophilias also may cause a severe form of preeclampsia, a pregnancy-related disorder that can pose serious risks for mother and baby, that is characterized by high blood pressure and protein in the urine.
