N normal phenotype
mortality/aging
• median and maximal survival of 269 and 438 days

behavior/neurological
• onset of tremor occurs after 1 year of age
• become increasingly ataxic
• starting around 9 months of age, mutants develop an abnormal gait with a shortened stride and splaying of the rear limbs
• eventually develop a hunched appearance and a side-to-side sway as they walk

nervous system
• levels of the small proteolipid, subunit C of mitochondrial ATP synthase (SCMAS ), are slightly elevated in the Purkinje cell layer of the cerebellar cortex at 4 months of age

cellular
• later onset of neuronal ceroid lipofuscinosis disease and slower progression than in homozygous Tpp1tm1Plob mice
