mortality/aging
• died approximately 30 days after birth

behavior/neurological
• retracted their hind feet and clenched their digits when suspended by tail
• decreased performance in an inclined-platform test with fewer mice reaching the top and taking longer to climb to the top of the platform, however, 63% of mutants remained on the platform suggesting that muscle strength is not impaired
• characterized by a progressive movement disorder beginning at P18
• displayed a progressive akinetic, rigid syndrome
• decreased mobility

cardiovascular system

cellular
• only mutant MEFs contained abnormal mitochondria and the increase in the number of abnormal mitochondria following mitochondrial stress was greater in mutant MEFs, indicating increased sensitivity to stress
• increased sensitivity to apoptosis induction by DNA-damaging agent etoposide
• significant increase in the susceptibility of cultured primary cortical neurons to excitotoxic stimuli

growth/size/body
• runted mice showed a general decrease in organ size
• failed to gain weight following weaning at P18

hematopoietic system

immune system

nervous system
• significant increase in the susceptibility of cultured primary cortical neurons to excitotoxic stimuli
• at P30, brain was approximately 75% of the weight of wild-type
• extracts from striata showed a significant decrease in the yield of mitochondrial citrate synthase suggesting decreased mitochondrial density
• at P20 and P30, observed selective loss of a population of striatal neurons, just lateral of the thalamus in a posteriomedial portion of the basal ganglia, and loss of terminals of the nigrostriatal pathway

homeostasis/metabolism
• significant increase in the susceptibility of cultured primary cortical neurons to excitotoxic stimuli

integument
• hair loss was occasionally seen in mutants after P18

endocrine/exocrine glands
