Sanfilippo syndrome

There is no specific treatment available for Sanfilippo syndrome. Experiments in animal models suggest that enzyme replacement may be used for treatment in the future.

Additional information and resources are available from the National MPS Society.

Severe retardation is the most important of the clinical problems. IQs may be below 50. Severe cases lead to death before 20 years of age.

In a minority of cases, Sanfilippo is compatible with a normal lifespan. The affected person may develop retinal degeneration leading to blindness, or may have seizures.
