Is Cohen Syndrome contagious?

Cohen Syndrome is not contagious; it is a rare genetic disorder caused by mutations in the VPS13B gene and cannot be transmitted through touch, proximity, or any form of social interaction. There is absolutely no risk of infection when living with, caring for, or spending time with an individual who has Cohen Syndrome.

What causes Cohen Syndrome?

Cohen Syndrome is an autosomal recessive genetic condition, meaning it is inherited when a child receives two copies of a mutated VPS13B gene—one from each parent. Because Cohen Syndrome is strictly genetic, it is impossible to "catch" it from another person or through environmental exposure. The condition affects multiple systems in the body, leading to a distinct clinical presentation that is present from birth, even if it is not diagnosed until later in childhood.

Why is there sometimes confusion regarding contagion?

Rare conditions like Cohen Syndrome are sometimes misunderstood by the public due to a lack of awareness. Because Cohen Syndrome involves complex developmental and physical features, such as intellectual disability, microcephaly, and distinctive facial features, those unfamiliar with the disorder may mistakenly assume the condition is an illness that could be spread. It is important to emphasize that Cohen Syndrome is a fixed genetic profile, not an infectious disease.

How does Cohen Syndrome impact daily life?

Living with Cohen Syndrome involves managing its specific, non-infectious symptoms. These often include:

• Developmental delays and intellectual disability.


• Distinctive facial features, such as down-slanting eyes and a short philtrum.


• Progressive high myopia (nearsightedness) and retinal dystrophy.


• Neutropenia (a low count of a type of white blood cell), which may affect immune response but is a symptom of the syndrome, not a communicable infection.


• Hypotonia (low muscle tone) and joint hypermobility.

Is there any environmental risk associated with Cohen Syndrome?

There are no environmental triggers for Cohen Syndrome. Unlike infectious diseases, which rely on pathogens like bacteria or viruses, Cohen Syndrome is determined at the moment of conception by the genetic code. You cannot contract it through food, water, air, or physical contact, and there is no social stigma that should be associated with this condition.
