mortality/aging
• rare, severely affected mice with nearly complete recombination die at 2 - 3 weeks of age

nervous system
• some lobules are reduced in size with lobes VI and VII most severely affected and often fused
• in a few rare cases with near complete recombination lobulation is severely aberrant
• cells are more densely packed at P4 and the layer is thicker at P10
• however, the number of proliferating cells per lobe length is not significantly different from controls
• cell numbers but not cell density are reduced in the anterior and posterior lobes
• the dendritic tree is often less elaborate
• cell numbers but not cell density are reduced in the anterior and posterior lobes
• contains fewer cells at P4
• however, layer thickness and cell density are similar to controls in adults
• virtually absent in a few rare cases with near complete recombination
• in less severely affected the vermis is slightly flattened
• at P4
• in a few rare cases with near complete recombination the cerebellum is severely reduced in size

behavior/neurological
• seen in severely affected mice with nearly complete recombination
