— Lysosomal storage disorders result in severe, multi-system dysfunction and frequently, early death. Currently, a number of lysosomal storage disorders are treated with enzyme replacement therapy (ERT), which requires periodic infusions of the deficient enzyme. However, in a number of instances the…

— Background
Niemann-Pick type C is a rare, progressive neurodegenerative disease characterized by accumulation of cholesterol and other lipids in the viscera and central nervous system. For cases caused by mutations in the NPC1 or NPC2 gene, egress of lipids from endosomes or lysosomes are impaired, resulting in clinical symptoms such as abnormal eye movements, hearing loss, cerebellar ataxia, difficulty swallowing, and cognitive impairment. However, patients with Neimann-Pick disease have highly variable clinical presentation and symptom progression, making diagnosis challenging.
Technology Summary
A panel of oxygenated forms of cholesterol (oxysterols) in plasma that can be used as a diagnostic test for Neimann-Pick type C1 disease. The mass spectrometry-based panel is able to discriminate between subjects with NPC1 and normal control subjects. The oxysterol biomarkers have clinical utility in newborn screening for early diagnosis of NP1C disease, as markers for disease severity, and as biomarkers to aid in evaluation of new therapies for NPC1.
Key Advantages
High sensitivity
Rapid diagnostic for screening infants
