mortality/aging
• mice were euthanized at 13 days of age due to no weight gain and seizures

nervous system
• 12 day old pups suffer seizures when touched by littermates
• E15.5 cortical neurons cultured in vitro die within 7 days of withdrawal of the anti-oxidant alpha-tocopherol
• this cell death occurs by a poorly defined death pathway involving the protein Aifm1
• damaged and pyknotic cells in the pyramidal layer of the CA3 region are found in mice 13 days of age
• parvalbumin-positive cells were largely lost from CA3 region due to apoptosis
• astrogliosis, apoptosis, and loss of parvalbumin-expressing cells occur in the somatosensory cortex of 13 day old mice
• astrogliosis occurs in the somatosensory cortex and the CA3 region of the hippocampus of 13-day old mice

growth/size/body
• mice cease weight gain starting at 8 days of age until being euthanized at 13 days of age

behavior/neurological
• is apparent at 10 days of age
• mice consistently bury themselves vertically in cage bedding
• 12 day old pups suffer seizures when touched by littermates

cellular
• E15.5 cortical neurons cultured in vitro die within 7 days of withdrawal of the anti-oxidant alpha-tocopherol
• this cell death occurs by a poorly defined death pathway involving the protein Aifm1
