nervous system
• mice exhibit vacuoles lesions in the olfactory bulb, the piriform cortex, several thalamic nuclei, some pons neurons, the choroid plexus, and the cerebellar roof nuclei
• at late stages
• motor neuron degeneration is observed in the ventral horns of the lumbar, thoracic, and cervical spinal cord as well as the brain stem
• degeneration is associated with vacuole formation in both dendrites and axons of motor neurons

• at 5 to 6 months of age, mice exhibit axial tremors
• at 5 to 6 months of age, mice exhibit asymmetric weakness of the limbs and when suspended by their tail exhibit difficulties extending and moving hindlimbs
• at 5 to 6 months of age, mice exhibit decreased spontaneous movement compared to wild-type mice
• eventually mice develop hindlimb paralysis

• at 5 to 6 months of age, mice exhibit muscle wasting particularly along the flanks
• mice exhibit spontaneous, positive sharp waves associated with denervation atrophy

• motor neurons exhibit mitochondrial degradation

• progressive

renal/urinary system
• mice exhibit vacuolization of epithelial cells in the proximal tubules of the kidney

• at 5 to 6 months of age
