Is CHARGE Syndrome contagious?

CHARGE syndrome is not contagious; it is a genetic condition and cannot be spread through touch, proximity, or social interaction. Because it is caused by specific gene mutations, there is zero risk of transmission to family members, caregivers, or peers.

What causes CHARGE syndrome?

CHARGE syndrome is a rare genetic disorder caused by a mutation in the CHD7 gene located on chromosome 8. In approximately 60% to 70% of individuals diagnosed with CHARGE syndrome, a pathogenic variant in this gene is identified. It is typically a de novo mutation, meaning it occurs spontaneously at the time of conception and is not inherited from the parents. It is a developmental condition that affects multiple organ systems, not an infectious disease.

Why is there confusion regarding contagion?

Because CHARGE syndrome involves complex medical needs—such as immune system vulnerabilities and frequent hospitalizations—people may mistakenly associate the condition with communicable illnesses. However, individuals with CHARGE syndrome are not "carriers" of a disease that others can catch. Their immune challenges are part of their specific genetic profile, not an external threat to others. Within the DiseaseMaps.org community, our 122 members emphasize that social isolation due to these misconceptions is a significant burden that families face.

Are there environmental triggers for CHARGE syndrome?

CHARGE syndrome is not caused by environmental exposures, viruses, or bacteria. It is a congenital condition present from birth. While environmental factors do not trigger the syndrome itself, those living with CHARGE syndrome may need to take extra precautions during flu season or around common illnesses due to their unique physiological vulnerabilities, such as airway abnormalities or hearing and vision impairments.

Common misconceptions about CHARGE syndrome

• Misconception: It can be caught from physical contact. Fact: It is purely genetic; touch is safe and encouraged.


• Misconception: It is caused by something the mother did during pregnancy. Fact: CHD7 mutations occur randomly.


• Misconception: It is a temporary illness. Fact: It is a lifelong, stable genetic condition.
