Summary Summary

Factor X deficiency is a rare condition that affects the blood's ability to clot. The severity of the condition and the associated signs and symptoms can vary significantly from person to person. Common features of factor X deficiency may include easy bruising, frequent nosebleeds, bleeding gums, blood in the urine, and prolonged bleeding after minor injuries. Affected women may also experience heavy menstrual bleeding and may have an increased risk for first trimester miscarriages.^[1]^[2] Acquired (non-inherited) factor X deficiency, which is the most common form of the condition, generally occurs sporadically in people with no family history of the condition. Acquired factor X deficiency has a variety of causes including liver disease, vitamin K deficiency, exposure to certain medications that affect clotting, and cancers. The inherited form of factor X deficiency (also called congenital factor X deficiency) is caused by changes (mutations) in the F10 gene and is inherited in an autosomal recessive manner.^[3] Treatment aims to control bleeding through intravenous (IV) infusions of plasma or concentrates of clotting factors.^[2]^[1]

Symptoms Symptoms

The Human Phenotype Ontology (HPO) provides the following list of features that have been reported in people with this condition. Much of the information in the HPO comes from Orphanet, a European rare disease database. If available, the list includes a rough estimate of how common a feature is (its frequency). Frequencies are based on a specific study and may not be representative of all studies. You can use the MedlinePlus Medical Dictionary for definitions of the terms below.
