involves: C57BL/6 * CBA * FVB
Key:
phenotype observed in females WTSI Wellcome Trust Sanger Institute
phenotype observed in males EuPh Europhenome
N normal phenotype
growth/size/body
• at end-stage, most mice display severe weight loss (>30%)

behavior/neurological
• at end-stage, severe locomotor deficits are exhibited
• at end-stage, loss of ability to hang in hanging wire test
• loss of grip strength at end-stage of disease

nervous system
• accumulation of argyrophilic neuronal debris is seen throughout medullary, pontine, and mesencephalic reticular formation up to zona incerta
• signs of reactive gliosis are seen at disease end-stage
• animals not displaying motor abnormalities show ubiquinated neurites in spinal cord
• in mice at end-stage, denervation is observed at neuromuscular synapses
• appears restricted to brainstem and spinal cord
• accumulation of argyrophilic neuronal debris is seen in spinal cord of mice at end-stage of disease; similar amounts are seen between left and right, and lumbar and cervical segments
• loss of motor neurons is detected at disease end-stage

muscle
• exhibited by most mice (67%) before 2 years of age; onset is observed at 539 days to more than 730 days with end stage reached at 591 to greater than 730 days

cellular
N
• mice do not develop mitochondrial swelling and vacuolization like G1 or G1del mutants (J:134095)
