Is Factor XIII Deficiency contagious?

Factor XIII Deficiency is not contagious under any circumstances and cannot be spread through touch, bodily fluids, or any form of social contact. It is a rare, lifelong bleeding disorder caused by a genetic mutation, not by a virus, bacteria, or other infectious agent.

What causes Factor XIII Deficiency?

Factor XIII Deficiency is primarily a hereditary condition. It occurs when an individual inherits mutations in the F13A1 or F13B genes, which are responsible for producing the protein necessary to stabilize blood clots. Because it is a genetic disorder, it is passed down from parents to children, usually through an autosomal recessive inheritance pattern. In rare cases, it can also be acquired later in life due to autoimmune reactions, but it remains a non-communicable medical condition.

Why is there confusion about contagion?

Because Factor XIII Deficiency involves blood and clotting issues, people unfamiliar with the condition may mistakenly fear it is an infectious blood-borne disease. This is a common misconception linked to the stigma surrounding blood disorders. Living with, hugging, or being in close proximity to someone with Factor XIII Deficiency poses absolutely no health risk to others.

How does Factor XIII Deficiency present?

The condition is characterized by a significant inability to form stable blood clots. Common experiences for those living with Factor XIII Deficiency include:

• Delayed bleeding after an injury or surgery, which may occur hours or even days later.


• Frequent, unexplained bruising or hematomas.


• Prolonged umbilical cord bleeding in newborns (a hallmark sign).


• A high risk of intracranial hemorrhage, which is why prophylactic treatment is often required.

Are there environmental triggers?

There are no environmental triggers for Factor XIII Deficiency, such as diet, climate, or hygiene habits. The condition is strictly biological. While stress or physical trauma can exacerbate bleeding episodes, the underlying deficiency of the clotting factor remains constant regardless of the environment.

Next steps

• Consult with a hematologist who specializes in rare coagulation disorders for personalized care.


• Connect with the Factor XIII Deficiency community on DiseaseMaps.org to share experiences with others who understand your journey.


• Discuss genetic counseling options with a specialist if you are planning to start a family.


• Carry a medical alert identification card to ensure emergency responders are aware of your specific clotting needs.
