We show that the NAGLU protein consists of a precursor and a mature form and that in SP MPSIIIB patients' fibroblasts only the precursor protein is present at 37°C.
Update of the spectrum of mucopolysaccharidoses type III in Tunisia: identification of three novel mutations and in silico structural analysis of the missense mutations.
To overcome these limitations, we delivered AAV9 vectors encoding for α-N-acetylglucosaminidase (NAGLU) to the Cerebrospinal Fluid (CSF) of MPSIIIB mice with the disease already detectable at biochemical, histological and functional level.
This will allow correction studies with NAG deficient Sanfilippo B cell lines and facilitate the development of enzyme replacement therapy for these patients.
This paper describes the expression and characterisation of wild-type recombinant NAG and the molecular characterisation of a previously identified R297X/F48L compound heterozygous MPS-IIIB patient with attenuated Sanfilippo syndrome.

This led to the identification of compound heterozygous mutations in NAGLU, compatible with the diagnosis of Mucopolysaccharidosis IIIB (MPS IIIB or Sanfilippo Syndrome type B).
The current study attempted to take advantage of this route for prenatal delivery of alpha-N-acetylglucosaminidase (Naglu) enzyme into the enzyme-deficient mouse model of Sanfilippo syndrome type B (MPS III B).
Sanfilippo type B syndrome (mucopolysaccharidosis type IIIB; MPS IIIB) is an autosomal recessive lysosomal storage disorder that is caused by defective alpha- N-acetylglucosaminidase (NAGLU).

RESOURCE DETAILS: Mucopolysaccharidosis IIIB (MPSIII, Sanfilippo syndrome type B) is a pediatric neurodegenerative disorder caused by a deficiency in NAGLU, an enzyme required for lysosomal degradation of heparin sulphate (HS).
