Is Rothmund-Thomson Syndrome contagious?

Rothmund-Thomson Syndrome is a rare genetic condition and is absolutely not contagious; it cannot be spread through touch, social interaction, or any form of physical contact. Because it is strictly caused by inherited mutations in specific genes, there is zero risk to family members, caregivers, or friends who interact with individuals living with this diagnosis.

What causes Rothmund-Thomson Syndrome?

Rothmund-Thomson Syndrome is a rare genodermatosis, most commonly caused by mutations in the RECQL4 gene. This gene provides instructions for producing a protein involved in DNA replication and repair. Because this is a genetic disorder, it is present from conception and is not caused by viruses, bacteria, or any external infectious agents.

Why is there confusion about contagion?

The misconception that Rothmund-Thomson Syndrome is contagious often stems from its visible physical symptoms, specifically the characteristic rash (poikiloderma) that typically appears on the face and limbs during infancy. Because the skin may appear inflamed or patterned, those unfamiliar with the syndrome may mistakenly perceive it as a contagious skin infection. It is important to emphasize that this skin manifestation is a lifelong developmental feature of Rothmund-Thomson Syndrome and poses no threat to others.

Is it safe to be around someone with this condition?

There is no risk whatsoever in living with, hugging, or sharing daily activities with a person who has Rothmund-Thomson Syndrome. The syndrome does not have environmental triggers that cause it to spread. Key facts regarding the nature of the condition include:

• It is inherited in an autosomal recessive pattern, meaning both parents must carry a copy of the mutated gene.


• It is not an infection, so there is no need for isolation or special sanitation protocols.


• Clinical management focuses on dermatological care and monitoring for increased cancer risks, such as osteosarcoma, not infection control.

Next steps

• Consult with a clinical geneticist to understand the specific genetic implications for your family.


• Connect with the 2 community members on DiseaseMaps.org who share lived experiences with Rothmund-Thomson Syndrome.


• Educate school staff, employers, or social circles using resources from the NIH GARD to dispel myths regarding contagion.
