Sanfilippo syndrome

Uncommon card · No. 85955

Sanfilippo syndrome, also known as mucopolysaccharidosis type III (MPS III), is a rare lifelong genetic disease that mainly affects the brain and spinal cord. It is caused by a problem with how the body breaks down certain large sugar molecules called glycosaminoglycans (also known as GAGs or mucopolysaccharides). In children with this condition, these sugar molecules build up in the body and eventually lead to damage of the central nervous system and other organ systems. Children with Sanfilippo syndrome do not usually show any problems at birth. As they grow, they may begin having trouble learning new things and might lose previously learned skills. As the disease progresses, they may develop seizures and movement disorders. Most children with Sanfilippo syndrome live into adolescence or early adulthood.
