Is Maroteaux-Lamy Syndrome contagious?

Maroteaux-Lamy syndrome (also known as Mucopolysaccharidosis type VI or MPS VI) is not contagious and cannot be spread from person to person through touch, saliva, or any other form of contact. It is a strictly genetic, metabolic condition caused by a deficiency in an enzyme, meaning it poses absolutely no risk of infection to family members, friends, or caregivers.

What causes Maroteaux-Lamy syndrome?

Maroteaux-Lamy syndrome is an autosomal recessive genetic disorder. It occurs when a person inherits two faulty copies of the ARSB gene, which is responsible for producing the enzyme arylsulfatase B. Without enough of this enzyme, the body cannot properly break down complex sugar molecules called glycosaminoglycans (GAGs), leading to their accumulation in various tissues and organs. Because it is rooted in DNA, Maroteaux-Lamy syndrome is present from conception and is not caused by environmental factors, viruses, or bacteria.

Why is there sometimes confusion regarding contagion?

Because Maroteaux-Lamy syndrome can cause visible physical changes, such as short stature, joint stiffness, or facial features that differ from the general population, people unfamiliar with rare diseases may mistakenly assume the condition is an infection. This stigma is entirely unfounded. You cannot "catch" Maroteaux-Lamy syndrome, and there is no risk in hugging, sharing meals, or living in the same household as someone diagnosed with the condition.

Understanding the nature of the condition

To clarify the biological reality of Maroteaux-Lamy syndrome, consider these key facts:

• It is a metabolic storage disorder, not an infectious illness.


• It is caused by a genetic mutation, affecting approximately 1 in 250,000 to 600,000 live births globally.


• There are no environmental "triggers" for the disease; the symptoms develop based on the underlying genetic deficiency.

Next steps

• Consult a metabolic geneticist for specialized management and family screening.


• Connect with the Maroteaux-Lamy syndrome community at DiseaseMaps.org to share experiences with others.


• Contact organizations like the National MPS Society for educational resources to share with schools or employers to combat stigma.
