• ♂: phenotype observed in males
• N: normal phenotype

homeostasis/metabolism

enhanced exercise endurance ( J:322912 )

• during the training stage of the treadmill test, mutant mice exhibit a stable performance at 6 and 12 months of age compared to controls which show decreased performance at 6 months

• during the fatigability stage of the treadmill test, mutant mice spend less time on the electrified grid than wild-type mice at 6 months of age

muscle

abnormal muscle tone ( J:322912 )

• 1-month-old mice show an increase in muscle tone

• however, no differences in grip test are seen in 1-18 month old mice and no muscle abnormalities are seen

behavior/neurological

behavior/neurological phenotype ( J:322912 )

N • behavior/neurological phenotype MP:0005386 mice do not show a difference on the rotarod and tail flick experiments show normal pain sensation

nervous system

nervous system phenotype ( J:322912 )

N • sciatic nerves in 18-month-old mice appear normal, nerve conduction velocities and action potential amplitudes in sciatic nerves are normal, and no signs of peripheral neuropathy are seen
