N normal phenotype
mortality/aging
• survival is increased to 3?6 months compared to from 1?2 months in Fig4 null mice not carrying the transgene

nervous system
N
• unlike in null mice not carrying the transgene, myelin sheath thinning is not seen
• intermediate level of autophagic inclusion bodies
• high pressure hydrocephalus is indicated by the compression of the cerebellum and hippocampus
• intermediate level compared to null mice not carrying the transgene
• intermediate level of degeneration compared to null mice not carrying the transgene
• degeneration of the cerebellar nuclei
• reduced at 4 and 14 months of age in the sciatic nerve but not as much as in null mice not carrying the transgene
