| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
|
• frequency of severe convulsions is higher than in controls but mortality is similar to controls following with 20 mg kainate/kg

| N |
• unlike patients with Alexander disease, megalencephaly is not detected
|
|
• increased frequency of severe convulsions and mortality following treatment with 20 mg kainate/kg compared to controls
• however sensitivity to pentylenetetrazole pilocarpine, or 4-aminopyridine induced seizures is similar to controls
|
|
• develop Rosenthal fibers in areas of the brain where GFAP aggregates are detected, such as the hippocampus
|
|
• following noise exposure, cochlear hair cell loss and degeneration is increased compared to controls
|
|
• GFAP aggregates are present in the cochlear nerve
|
|
• following noise exposure, cochlear hair cell loss and degeneration is increased compared to controls
|
|
• more pronounced hearing loss at 4kHz is seen in 5 week old mutants at 1 and 4 weeks after noise exposure
• following noise exposure, in response to click stimulus ABR peaks disappear from wave I and changes in the intensity-latency function indicate cochlear damage
|
| N |
• unlike patients with Alexander disease, spontaneous convulsions are not observed
|
|
• increased frequency of severe convulsions and mortality following treatment with 20 mg kainate/kg compared to controls
• however sensitivity to pentylenetetrazole pilocarpine, or 4-aminopyridine induced seizures is similar to controls
|
|
• develop Rosenthal fibers in areas of the brain where GFAP aggregates are detected, such as the hippocampus
