Living with Factor XIII deficiency

A rare bleeding disorder, usually starting in newborns, with long bleeding after injuries and bleeding into joints and muscles.

Understanding Factor XIII deficiency

Factor XIII deficiency is a rare bleeding disorder with an inherited form and a milder form acquired during life.

In the inherited form, signs begin soon after birth, often with bleeding from the umbilical cord stump. Bleeding can occur after surgery or minor injury, or into joints and muscles, causing pain. Women may have heavy periods and repeated miscarriages. Bleeding inside the skull is a risk. The acquired form is milder and appears later in life.

Signs & symptoms

GARD describes these common symptoms in its summary:

  • Bleeding from the umbilical cord stump
  • Long bleeding after surgery or injury
  • Bleeding into joints or muscles
  • Nosebleeds and bleeding gums
  • Easy bruising
  • Slow wound healing

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

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

  2. See a specialist

    Your doctor may refer you to a specialist who knows rare conditions.
