Mucopolysaccharidosis Type III
Sanfilippo syndrome, also known as mucopolysaccharidosis type III (MPS III), is a rare lifelong genetic disease that mainly affects the Human brain, 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. Signs and symptoms The age of onset, severity, and progression of the disease can vary greatly between patients with different subtypes and within the same subtyp ...

Mucopolysaccharidosis
Mucopolysaccharidoses are a group of metabolic disorders caused by the absence or malfunctioning of lysosomal enzymes needed to break down molecules called glycosaminoglycans (GAGs). These long chains of sugar carbohydrates occur within the cells that help build bone, cartilage, tendons, corneas, skin and connective tissue. GAGs (formerly called mucopolysaccharides) are also found in the fluids that lubricate joints. Individuals with mucopolysaccharidosis either do not produce enough of one of the eleven enzymes required to break down these sugar chains into simpler molecules, or they produce enzymes that do not work properly. Over time, these GAGs collect in the cells, blood and connective tissues. The result is permanent, progressive cellular damage which affects appearance, physical abilities, organ and system functioning. The mucopolysaccharidoses are part of the lysosomal storage disease family, a group of genetic disorders that result when the lysosome organelle in anim ...
