Factor VII deficiency

Prevalence
Prevalence estimates on Rare Medical Network websites are calculated based on data available from numerous sources, including US and European government statistics, the NIH, Orphanet, and published epidemiologic studies. Rare disease population data is recognized to be highly variable, and based on a wide variety of source data and methodologies, so the prevalence data on this site should be assumed to be estimated and cannot be considered to be absolutely correct.

Inheritance

Autosomal dominant A pathogenic variant in only one gene copy in each cell is sufficient to cause an autosomal dominant disease

no.svg

Autosomal recessive Pathogenic variants in both copies of each gene of the chromosome are needed to cause an autosomal recessive disease and observe the mutant phenotype

X-linked
dominant X-linked dominant inheritance, sometimes referred to as X-linked dominance, is a mode of genetic inheritance by which a dominant gene is carried on the X chromosome.

X-linked
recessive Pathogenic variants in both copies of a gene on the X chromosome cause an X-linked recessive disorder

no.svg

Mitochondrial or multigenic Mitochondrial genetic disorders can be caused by changes (mutations) in either the mitochondrial DNA or nuclear DNA that lead to dysfunction of the mitochondria and inadequate production of energy.

Multigenic or multifactor Inheritance involving many factors, of which at least one is genetic but none is of overwhelming importance, as in the causation of a disease by multiple genetic and environmental factors.

Summary

Factor VII deficiency is a rare bleeding disorder. The age of onset and severity varies from person to person. While severe cases may become apparent in infancy, very mild cases may never cause any bleeding problems. Signs and symptoms may include nosebleeds; easy bruising; bleeding gums; excessive or prolonged bleeding after injury or surgery; and heavy or prolonged menstrual bleeding in women. Some people with factor VII deficiency may have bleeding in the joints or blood in the urine. In very severe cases, factor VII deficiency can be life-threatening, causing bleeding inside the skull or digestive tract.[1]

Factor VII deficiency may be inherited or acquired. The inherited from is caused by mutations in the F7 gene and inheritance is autosomal recessive. The acquired form is not inherited and may be caused by liver disease, blood cell disorders, certain drugs, or vitamin K deficiency.[1] Treatment for bleeding may include intravenous infusions of normal plasma, concentrated factor VII, or genetically-made (recombinant) factor VII. Those with acquired factor VII deficiency due to vitamin K deficiency may take vitamin K by mouth, injection, or infusion.[2]

Symptoms

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

Diagnosis

Making a diagnosis for a genetic or rare disease can often be challenging. Healthcare professionals typically look at a person’s medical history, symptoms, physical exam, and laboratory test results in order to make a diagnosis. The following resources provide information relating to diagnosis and testing for this condition. If you have questions about getting a diagnosis, you should contact a healthcare professional.

Testing Resources

  • The Genetic Testing Registry (GTR) provides information about the genetic tests for this condition. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional.

Treatment

FDA-Approved Treatments

The medication(s) listed below have been approved by the Food and Drug Administration (FDA) as orphan products for treatment of this condition. Learn more orphan products.

  • Coagulation Factor VIIa (Recombinant)(Brand name: NovoSeven RT) Manufactured by Novo Nordisk, Inc.
    FDA-approved indication: March 2005, NovoSeven RT was approved for the prevention of bleeding in surgical interventions or invasive procedures in hemophilia A or B patients with inhibitors to Factor VIII or Factor IX. Previously in March 1999, NovoSeven RT was approved for the treatment of bleeding episodes in hemophilia A or B patients with inhibitors to Factor VIII or Factor IX. July 2014, NovoSeven RT was approved for the treatment of bleeding episodes and peri-operative management in adults and children with Glanzmann's thrombasthenia with refractoriness to platelet transfusions, with or without antibodies to platelets.
