Explore Treatments for Factor X Deficiency

Factor X deficiency (also known as Stuart-Prower deficiency) is a rare bleeding disorder caused by low or missing levels of a blood clotting protein called “factor X.” This condition affects both males and females equally. The severity of symptoms depends on how much factor X is present in the blood. Common signs include easy bruising, frequent nosebleeds, bleeding gums, blood in the urine and prolonged bleeding after minor injuries. Women with Factor X deficiency may also experience heavy menstrual bleeding and have a higher risk of miscarriage during the first trimester. Most cases of Factor X deficiency are acquired (not inherited). Acquired Factor X deficiency can occur due to liver disease, vitamin K deficiency, certain medications that affect clotting, or some types of cancer.
