N normal phenotype
behavior/neurological
• mice show deficits on the accelerating rotarod at 26 weeks of age but not at earlier time points
• mice exhibit alterations in gait, with increases in both step angle variance and stance width

nervous system
• cerebellar N-acetylaspartate concentrations decline with age
• progressive cerebellar degeneration
• mice exhibit altered metabotropic glutamate receptor 1alpha localization at Purkinje cell dendritic spines
• thinning of the cerebellar molecular layer
• mice show a 35% decrease in the metabotropic glutamate receptor 1alpha-mediated response to parallel fiber stimulation but little change in AMPA responsiveness compared with controls
• the metabotropic glutamate receptor 1alpha-mediated long term potentiation (LTP) is absent
• mice show reduced amplitude and LTP of long-latency patches
