Living with Hereditary factor XIII deficiency disease

An extremely rare inherited bleeding disorder in which blood clots are not stabilized well.

Understanding Hereditary factor XIII deficiency disease

Hereditary factor XIII deficiency disease is an extremely rare inherited disorder in which blood clots do not form properly, causing abnormal bleeding.

Factor XIII helps stabilize a blood clot. Without enough, wounds heal poorly and blood can seep into soft tissues, causing pain and swelling. Internal bleeding can occur, and about 25 percent of affected people have bleeding in the brain. Acquired forms have been reported with liver failure, inflammatory bowel disease, and myeloid leukemia.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Bleeding from the umbilical stump
  • Easy bruising
  • Bleeding under the skin
  • Bleeding into joints
  • Bleeding in the mouth
  • Bleeding in the brain

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include blood and bone marrow specialists and genetic specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  • Connect with National Bleeding Disorders Foundation
  • Keep notes on symptoms, changes and questions for appointments
  • Ask about patient registries that help research
  • Look into financial aid and travel resources for care visits
Bring these questions to your next doctor visit
Which gene change do I have, F13A1 or F13B?
How can bleeding in the brain be watched for or prevented?
What should we do for surgery, dental work, or pregnancy?

Quick facts

Symptoms usually startany time in life
InheritanceAutosomal Recessive

It is usually caused by changes in the F13A1 gene, and sometimes the F13B gene. It is usually autosomal recessive, so a child inherits a changed copy of the gene from each parent.
