Is Cardiofaciocutaneous / Cfc Syndrome contagious?

Cardiofaciocutaneous (CFC) syndrome is not contagious; it is a rare genetic condition caused by mutations in genes involved in the RAS/MAPK signaling pathway. Because it is strictly a result of an individual's genetic makeup, there is zero risk of transmitting Cardiofaciocutaneous syndrome through touch, social interaction, or shared environments.

What causes Cardiofaciocutaneous (CFC) syndrome?

Cardiofaciocutaneous syndrome is caused by a de novo (spontaneous) mutation in one of several genes, most commonly BRAF, MAP2K1, MAP2K2, or KRAS. These genes provide instructions for proteins that regulate cell growth and division. Because these mutations occur during the formation of reproductive cells or early embryonic development, Cardiofaciocutaneous syndrome cannot be "caught" or spread to others.

Why is there confusion regarding the contagiousness of CFC syndrome?

Rare conditions like Cardiofaciocutaneous syndrome are sometimes misunderstood by the general public due to their complex physical presentations, which can include unique facial features or skin abnormalities. People may mistakenly associate these physical traits with infectious diseases. It is important to emphasize that Cardiofaciocutaneous syndrome is a lifelong genetic condition, not an illness that can be transmitted to family members, caregivers, or friends.

Is it safe to interact with someone who has Cardiofaciocutaneous syndrome?

Yes, it is completely safe to live with, touch, and care for an individual with Cardiofaciocutaneous syndrome. There are no environmental triggers that cause the condition to develop in others, and there are no precautions needed to protect oneself from the disease. Social interaction is actually highly encouraged, as individuals with Cardiofaciocutaneous syndrome benefit greatly from supportive, inclusive, and connected communities like the 36 members currently sharing their experiences on DiseaseMaps.org.

Key facts about the nature of CFC syndrome

• Genetic Origin: Primarily caused by sporadic mutations in the RAS/MAPK pathway.


• Non-Communicable: It is impossible to transmit the condition via saliva, blood, skin contact, or airborne droplets.


• No Environmental Triggers: Exposure to specific surroundings or pathogens does not cause or exacerbate the fundamental genetic mechanism of the syndrome.


• Prevalence: It is extremely rare, with estimated prevalence rates often cited as less than 1 in 100,000 individuals.

Next steps

• Consult a clinical geneticist to discuss the specific genetic mutation identified in your family.


• Connect with the Cardiofaciocutaneous syndrome community at DiseaseMaps.org to share support and resources.


• Educate family and school staff using materials from the CFC International foundation to dispel myths about contagion.
