Is Freeman Sheldon Syndrome contagious?

Freeman Sheldon Syndrome is a rare genetic disorder and is absolutely not contagious. It cannot be spread through touch, physical contact, or proximity, as it is caused by specific gene mutations rather than infectious agents like viruses or bacteria.

What causes Freeman Sheldon Syndrome?

Freeman Sheldon Syndrome, often referred to as "whistling face syndrome," is a congenital myopathy. It is caused by mutations in the MYH3 gene, which provides instructions for making a protein essential for muscle contraction. Because Freeman Sheldon Syndrome is fundamentally a genetic condition, there are no environmental triggers that can cause a person to "catch" it. It is present at birth, and the underlying biological mechanism is entirely internal to the individual's genetic code.

Is Freeman Sheldon Syndrome hereditary?

The inheritance pattern of Freeman Sheldon Syndrome can be either autosomal dominant or autosomal recessive, depending on the specific mutation. Most cases occur due to a new (de novo) mutation in the MYH3 gene. Because the condition is strictly genetic, family members and friends living with someone who has Freeman Sheldon Syndrome are at zero risk of contracting the condition. There is no possibility of transmission through bodily fluids, shared items, or air.

Why is there stigma surrounding this condition?

People may mistakenly assume Freeman Sheldon Syndrome is contagious due to the physical differences in facial structure and joint contractures associated with the condition. Misunderstandings about rare diseases often lead to social isolation; however, it is important to emphasize the following facts:

• Freeman Sheldon Syndrome is not an infection.


• There is no risk to caregivers or peers from physical interaction.


• The physical characteristics of Freeman Sheldon Syndrome are solely due to muscle and bone development, not illness or contagion.

Next steps

• Connect with the 32 members of the Freeman Sheldon Syndrome community at DiseaseMaps.org to share experiences and find support.


• Consult with a clinical geneticist to discuss genetic testing and family planning options.


• Work with a multidisciplinary medical team, including orthopedists and physical therapists, to manage symptoms effectively.
