mortality/aging
• mice die during the third postnatal week

nervous system
• at P7 and P15, the number of post-mitotic oligodendrocytes is reduced in the optic nerve compared to in wild-type mice
• at P21, the number of mature oligodendrocytes is reduced in the optic nerve compared to in wild-type mice
• fewer cells are found in the corpus callosum compared to in wild-type mice
• mice do not exhibit an appreciable postchiasmatic optic tract unlike wild-type mice
• brainstem bulk is decreased compared to in wild-type mice
• in the cerebellum
• neurons in the cerebellum and spinal cord contain vacuoles unlike in wild-type mice
• the density of myelinated axons in the ventral white matter of the spinal cord and in the optic nerve is decreased compared to in wild-type mice
• however, myelin density and structures on the sciatic nerve are normal
• the optic nerve is thin with reduced numbers of mature oligodendrocyte compared to in wild-type mice
• optic nerves exhibit abnormal swellings and axonal spheroids unlike in wild-type mice
• mice exhibit an increase in optic nerve apoptosis compared with wild-type mice
• mice exhibit handling-induced tonic-clonic seizures unlike wild-type mice
• mice exhibit handling-induced tonic-clonic seizures unlike wild-type mice
• myelin maturation is delayed compared to in wild-type mice
• optic nerve myelination is attenuated compared to in wild-type mice
• however, mature myelin forms and has relatively normal structure and organization

behavior/neurological
• severe
• uncoordinated
• mice exhibit handling-induced tonic-clonic seizures unlike wild-type mice
• mice exhibit handling-induced tonic-clonic seizures unlike wild-type mice

growth/size/body

vision/eye
• the optic nerve is thin with reduced numbers of mature oligodendrocyte compared to in wild-type mice
• optic nerves exhibit abnormal swellings and axonal spheroids unlike in wild-type mice
