N normal phenotype
• survival rate at 13 months is 33%
• some mice start to die at 5 months of age and survival rate at 13 months is about 33%

• clasping behavior is seen after 8.5 months of age
• mice are unbalanced on the rotarod while running and exhibit a higher tendency to fall off during three consecutive days at the end stage
• mice show weaker grasping strength after 8.5 months of age that becomes progressively worse with age
• mice show disordered and shorter stride length, dragging, and uneven step patterns and unbalanced gaits when walking through a tunnel at the end stage
• in aged mice

nervous system
• nuclear aggregates, intranuclear aggregates, and neuropil aggregates and inclusion bodies are seen in the cortex and striatum regions at 12 months of age, but not at 2 months
• more nuclear aggregates and inclusion bodies are seen in the striatum while neuropil aggregates are predominately seen in the cortex region
