Factor X deficiency is a disorder caused by too little of a protein called factor X in the blood. It leads to problems with blood clotting (coagulation).
Alternative NamesStuart-Prower deficiency
Causes, incidence, and risk factorsWhen you bleed, the body launches a series of reactions that help the blood clot. This is called the coagulation cascade. The process involves special proteins called coagulation factors. (Factor X is a coagulation factor.) Each factor's reaction triggers the next reaction. The final product of the coagulation cascade is the blood clot. When certain coagulation factors are missing, the chain reaction does not take place normally.
Factor X deficiency is often caused by a defect of the factor X gene that is passed through families. This is called inherited factor X deficiency. Bleeding ranges from mild to severe.
Factor X deficiency may also develop due to another condition or use of medications. This is called aquired factor X deficiency. Acquired factor X deficiency is common. It may be caused by a lack of vitamin K, amyloidosis, severe liver disease, and use of drugs that prevent clotting (anticoagulants such as warfarin or coumadin). Some newborns are born with vitamin K deficiency. See: Vitamin k deficiency bleeding in newborns
Women with factor X deficiency may have very heavy menstrual bleeding and bleeding after delivery. Newborn boys with the condition may have longer-than-normal bleeding after circumcision.
Inherited factor X deficiency affects 1 out of every 500,000 people.
SymptomsTreatment for the bleeding disorder involves infusions of fresh frozen plasma or factor X concentrates into the blood during sudden (acute) episodes or before surgery.
Support GroupsYou can ease the stress of illness by joining a support group where members share common experiences and problems.
Expectations (prognosis)The outcome is usually good with mild disease or treatment.
Inherited factor X deficiency is a life-long condition.
The outlook for acquired factor X deficiency depends on the underlying cause. If it is caused by liver disease, the outcome depends on how well your liver disease is controlled. Taking vitamin K supplements will treat vitamin K deficiency. If the disorder is caused by amyloidosis, surgery is done to remove the spleen.
ComplicationsSevere bleedingor sudden loss of blood (hemorrhage) can occur. The joints may get deformed in severe disease from many bleeds.
Calling your health care providerCall your health care provider, go to the emergency room, or call the local emergency number (such as 911) if you have an unexplained or severe loss of blood.
PreventionInherited factor X deficiency is rare. There is no known prevention.

Hemophilia primarily includes two main types: Hemophilia A and Hemophilia B. Hemophilia A, the most common type, is caused by a deficiency of factor VIII, while Hemophilia B, also known as Christmas disease, results from a deficiency of factor IX. A rarer type, Hemophilia C, is linked to a deficiency of factor XI and is less severe than the other two types. Each type is inherited in an X-linked recessive manner, primarily affecting males.

Color deficiency is a more accurate term for "color blindness". It is an inability or a reduced ability to detect and distinguish between colors. Most often it is caused by a factor of the X sex chromosome which prevents the development of one or more types of retinal cones--the sensors within your eye that detect color. Damage to the eyes or brain can also cause color deficiency.

Yes, the disorder you are referring to is hemophilia A, which is caused by a deficiency or missing factor VIII in the blood. This results in impaired blood clotting and leads to prolonged bleeding after injury or surgery. It is inherited in an X-linked recessive pattern, meaning it predominantly affects males.
