Abstract
Mutations in individuals with the lysosomal storage disorder Niemann-Pick disease, type C1 (NPC1) are heterogeneous, not localized to specific protein domains, and not correlated to time of onset or disease severity. We demonstrate direct correlation of the time of neurological symptom onset with the severity of lysosomal defects in NPC1 patient-derived fibroblasts. This is a novel assay for NPC1 individuals that may be predictive of NPC1 disease progression and broadly applicable to other lysosomal disorders.
