Is Branchio Oto Renal Syndrome contagious?

Branchio Oto Renal (BOR) syndrome is a genetic condition and is not contagious in any way. You cannot catch Branchio Oto Renal syndrome through touch, proximity, sharing items, or any form of social contact, as it is caused by mutations in specific genes rather than by infectious pathogens like viruses or bacteria.

What causes Branchio Oto Renal syndrome?

Branchio Oto Renal syndrome is an autosomal dominant genetic disorder caused by mutations in the EYA1, SIX1, or SIX5 genes. Because it is inherited, it is present from conception. It is not caused by environmental factors, lifestyle choices, or infections, meaning it cannot be transmitted to family members, friends, or classmates.

Why is there confusion about contagion?

Rare conditions like Branchio Oto Renal syndrome are often misunderstood because the public is generally unfamiliar with genetic disorders. Because Branchio Oto Renal syndrome involves physical features—such as branchial cleft cysts, ear malformations, or hearing loss—some people may mistakenly assume these traits are the result of an illness that could be spread. It is important to clarify that these symptoms are structural developmental differences, not symptoms of an infectious disease.

Is it safe to interact with someone who has Branchio Oto Renal syndrome?

Yes, it is completely safe to interact with, touch, or live with someone who has Branchio Oto Renal syndrome. There is zero risk of transmission. Being part of the DiseaseMaps.org community, where 33 members currently share their experiences, helps foster understanding and reduces the unnecessary stigma that patients and families sometimes face regarding the nature of their diagnosis.

Key facts about the nature of Branchio Oto Renal syndrome

• Genetic Origin: It is caused by mutations in the EYA1, SIX1, or SIX5 genes.


• Inheritance: It follows an autosomal dominant pattern, meaning a parent with the condition has a 50% chance of passing it to their child.


• Non-Infectious: It is biologically impossible to transmit Branchio Oto Renal syndrome to another person.


• Prevalence: It is estimated to affect approximately 1 in 40,000 people globally.
