Mucopolysaccharidosis type IIIb (MPS 3b)

Mucopolysaccharidosis IIIb or Sanfilippo syndrome type B is a progressive autosomal recessive hereditary disease known in Schipperke Dogs. It is a lysosomal storage disorder characterized by deficient activity of enzyme alpha-N-acetylglucosaminidase, that causes accumulation of specific glycosaminoglycans in lysosomes. The disease symptoms show at around two years of age. Clinical signs are consistent with cerebellar disease and include tremors, episodes of stumbling, dysmetria, hind limb ataxia and a wide-based stance with truncal swaying. Mildly dystrophic corneas and small peripheral foci of retinal degeneration can also be observed. The disease progresses over time which leads to euthanasia before six years of age.
