MPS III Sanfilippo Syndrome Plasma

MPS III Sanfilippo Syndrome Plasma for Lysosomal Storage Disease Research

MPS III Sanfilippo Syndrome Plasma is collected from IRB-consented donors with a clinically confirmed diagnosis of mucopolysaccharidosis type III and processed under rigorous, standardised SOPs with donor screening and sample quality checks. Plasma is acellular, so this product is supplied for soluble-analyte work — glycosaminoglycan quantification, immunoassay, proteomics and metabolomics — in standard or custom volumes with de-identified clinical annotation.

Why MPS III Plasma for Genetic Disease Research

Sanfilippo syndrome is a monogenic autosomal recessive lysosomal storage disease. A deficiency in one of four enzymes required for the stepwise degradation of heparan sulfate blocks the catabolic pathway, so partially degraded heparan sulfate accumulates in lysosomes throughout the body and particularly in the central nervous system. The consequence is progressive neurodegeneration with developmental regression, behavioural disturbance and loss of acquired skills. This is a defined genetic and biochemical defect, not an autoimmune process.

• Heparan sulfate accumulation — the primary storage material is measurable in the circulation, making plasma glycosaminoglycan quantification the most direct biochemical readout of the underlying defect.
• Four enzyme subtypes, one pathway — MPS IIIA (SGSH, heparan-N-sulfatase), IIIB (NAGLU, alpha-N-acetylglucosaminidase), IIIC (HGSNAT, acetyl-CoA:alpha-glucosaminide N-acetyltransferase) and IIID (GNS, N-acetylglucosamine-6-sulfatase) each block a different step in heparan sulfate degradation.
• Non-reducing-end structural signatures — the specific enzyme deficiency determines the terminal structure of the accumulated heparan sulfate fragments, which is central to subtype-discriminating biomarker methods.
• Secondary consequences of storage — lysosomal dysfunction, disrupted autophagy and secondary accumulation of other substrates generate downstream analytes detectable in the acellular compartment.
• Neurodegeneration markers — circulating markers of neuroaxonal injury and neuroinflammation are of active interest as peripherally accessible surrogates for a primarily central disease.
• Therapeutic development context — enzyme replacement, gene therapy and substrate reduction programmes all need plasma heparan sulfate and related analytes as pharmacodynamic endpoints, since a plasma sample can be collected repeatedly where CSF cannot.
