|
• mice survive up to approximately 14 weeks

behavior/neurological
nervous system
|
• mice show progressive degeneration of granule cell neurons such that the inner granule layer is largely devoid of granule cell neurons at P48
|
|
• P95 mice have severely atrophic cerebellum with the inner granule layer largely devoid of granule cell neurons at P48
• however, cerebellar phenotypes are less severe than in homozygous Tubb4aJit mice
|
|
• reduction in white matter tracts such as corpus callosum, anterior commissures, and striatal fascicles at P95
|
|
• mice show progressive degeneration of myelin with reduced myelin at P48 and P95, however reduction in myelin is not as severe as in in homozygous Tubb4aJit mice
• cerebellum is severely demyelinated at P95
