N normal phenotype
mortality/aging
• mice die at 2 to 4 months of age

nervous system
• at P15, Bergmann glial cell processes are severely disorganized
• mice exhibit a delay in the migration of cells from the external granule layer to the internal granule layer
• at P9, the external granule cell layer contains more granule cells than in wild-type mice
• unlike in wild-type mice, granule cells are maintained at P17 but migrate to the internal granule cell layer by P21
• however, cell proliferation within the external granule layer is normal

growth/size/body

cellular
• at P15, Bergmann glial cell processes are severely disorganized
• mice exhibit a delay in the migration of cells from the external granule layer to the internal granule layer
