What is Sanfilippo Syndrome (MPS III) ?

Sanfilippo Syndrome or MPSIII, is one of the 6 mucopolysaccharidoses disorders. MPS disorders are a group of rare genetic disorders caused by the deficiency of one of the lysosomal enzymes. These enzymes are responsible for breaking down the complex carbohydrate-Hepran Sulfate (HS). HS builds up and is stored in the lysosome of the cell, causing catastrophic health problems leading to death.
