N normal phenotype
mortality/aging
• male mice have a 22% increase in lifespan compared to transgene-negative Npc1 homozygotes which die around 95 days of age

growth/size/body
• animals lose weight more slowly than transgene positive Npc1 homozygotes; at all time points after the 4 weeks, weight differences are significantly different
• transgene-positive animals show a trend to increased weight retention; retardation in weight loss is more pronounced for males relative to females

homeostasis/metabolism
• 80-day-old mice have reduced levels of GM2 and GM3 gangliosides (by 45 and 32%) in the cerebral cortex compared to transgene-negative Npc1 homozygotes
