Is Fraser Syndrome contagious?

Fraser syndrome is a rare genetic condition and is absolutely not contagious; it cannot be spread through touch, social contact, or environmental exposure. It is caused by specific genetic mutations and is present at birth, meaning there is zero risk of transmission to family members, caregivers, or peers.

What causes Fraser syndrome?

Fraser syndrome is an autosomal recessive genetic disorder, meaning a child must inherit two copies of a mutated gene—typically the FRAS1, FREM2, or GRIP1 genes—to develop the condition. Because it is rooted in the individual's genetic code, Fraser syndrome is not caused by viruses, bacteria, or external environmental factors. There are no known triggers that can "cause" the disease after birth, as the developmental impacts occur during fetal gestation.

Why is there confusion about the transmission of Fraser syndrome?

The confusion surrounding Fraser syndrome often stems from its visible physical manifestations, such as cryptophthalmos (hidden eyes), syndactyly (webbing of fingers or toes), and renal agenesis. Because rare conditions are poorly understood by the general public, people may mistakenly associate physical abnormalities with infectious diseases. It is important to emphasize that Fraser syndrome involves structural developmental differences, not an active infection, and it carries no social or medical risk to those interacting with a patient.

Common misconceptions and facts about Fraser syndrome

To provide clarity for the 17 members of our Fraser syndrome community at DiseaseMaps.org and their families, please note the following facts:

• No transmission risk: You cannot "catch" Fraser syndrome by touching, sharing food, or living in the same home.


• Genetic basis: The condition occurs in approximately 1 in 200,000 to 1 in 500,000 births.


• Social safety: Children with Fraser syndrome can attend school and participate in all social activities without any risk to others.

Next steps

• Consult with a clinical geneticist to understand the specific inheritance patterns of Fraser syndrome.


• Connect with the Fraser syndrome community at DiseaseMaps.org to share experiences and combat social stigma.


• Provide medical literature to school administrators or community members to dispel myths regarding contagion.
