mortality/aging
• mice die within the first day after birth
|
nervous system
• not clearly observed
|
• at the caudate-putamen level
|
• enlarged 60% to 70% and closed
|
• the corpus callosum is interrupted at the caudate-putamen level and contains an unusual number of cell bodies unlike in wild-type mice
|
• at E19, the hippocampus lacks normal laminar organization with pyramidal neurons scattered and separated unlike in wild-type mice
|
• the dentate gyrus lacks cell organization unlike in wild-type mice
|
• unlike in wild-type mice, the neuronal cell lamination of the cerebral cortex is lost and there is an unusual number of cell bodies in the corpus callosum
• the thickness of cortical region is varied unlike in wild-type mice
• in some mice the cerebral cortex is half the size as in wild-type mice
|
• disorganized layers
|
• at E19, the wide band of Purkinje cells normally present is absent
|
behavior/neurological
• on limbs
