mortality/aging
• life span of 1-4 months

behavior/neurological
• decline in motor functions begins before 3 months of age
• impaired performance in a rotarod test is significantly greater than in either singly homozygous mouse
• poor performance in a "wire hang" test
• decreased horizontal activity

nervous system
• vacuolated macrophage found throughout the central nervous system
• swollen cell bodies in all neurons of the brain, trigeminal ganglia, and dorsal root ganglia
• storage cells in addition to neurons found througout the central nervous system and peripheral nerves
