Lysosomal Storage Disease

Lysosomal Storage Disease enters the Adult Cognitive Disease corpus through the work of Alan Snow (submission 136), and is indexed here as one of the concepts that submission puts to work.

The argument it belongs to

Alan Snow's submission is summarised in this corpus as:

The accumulation and structural modification of Heparan Sulfate Proteoglycans (HSPGs), specifically the basement membrane proteoglycan perlecan, constitute the singular obligate initiating event that drives amyloidosis, tauopathy, neuroinflammation, and synaptic failure in Alzheimer's disease. HSPGs act as obligate scaffolds for amyloid nucleation, and AD-specific perlecan splice variants create 'super-nucleators' that template plaque formation.

The source paper puts the concept to work directly:

HS GAG Accumulation in Neurons as Observed in Mucopolysaccharidosis Diseases Lead to Misfolded Protein Accumulation Including Aβ, Tau Protein, α-Synuclein and Prion Protein (PrP) Mucopolysaccharidoses (examples Hunter’s syndrome- MPS II and Hurler’s syndrome; MPS I) are lysosomal storage diseases that are inborn errors in the metabolism of GAGs.
