N normal phenotype
behavior/neurological
• balance maintenance during rotarod test for example is impaired from 4 months
• in mice >17 months of age, abnormal gait is seen, due to impaired hindlimb coordination

nervous system
• axonal swellings resulting from accumulations of organelles and neurofilaments are observed
• distal axonopathy of spinal and peripheral axons characterized by swelling and degeneration
• associated with abnormal mitochondria
• impairment of retrograde axonal transport in symptomatic mice
