Mucopolysaccharidosis type IIIa (MPS 3a)

Mucopolysaccharidosis type IIIa or Sanfilippo syndrome type A is an autosomal recessive hereditary disease described in Dachshund. It is characterized by deficiency of lysosomal exohydrolase, a heparan sulphate sulphamidase (HSS), which is crucial for metabolism of heparan sulphate. That deficiency results in intralysosomal accumulation of heparan sulphate. The symptoms include decreased HSS catalytic activity in liver and progressive neurologic defects, such as spinocerebellar ataxia.
