Mucopolysaccharidosis type III

This type, also known as Sanfilippo syndrome, is an autosomal recessive hereditary disease. The clinical features and biochemical abnormalities of this type are different from those of type Ⅰ and type Ⅱ, which are characterized by severe degree of insensitivity, but relatively mild pathological changes. The difference from type I is that the appearance is not like Chengyu disease, the dwarf is not obvious, and there are no complications such as corneal opacity or heart disease. Elbow and knee joints have mild contractures. Even with hepato-splenomegaly, it is mild.
