mortality/aging
N |
• mice exhibit normal survival up to 1 year of age, unlike Camta1tm1.2Eno homozygotes
|
growth/size/body
• runting is seen in only a subset of mice and is less severe than in Camta1tm1.2Eno homozygotes
|
behavior/neurological
• severe ataxia by 6 weeks of age, as determined by several motor tasks and general observation
• fully penetrant at >3 months of age
|
• impaired motor performance on the accelerating rotarod and beam walk tests by 6 weeks of age
• by 3 months, loss of motor coordination is fully penetrant and more pronounced in the hindlimbs
|
nervous system
• Purkinje cells are reduced in size and disarrayed at 6 months of age
|
• severe loss of Purkinje cells at 3 months of age
• however, Purkinje cell number is normal at age 2-3 weeks of age
|
• significant decrease in the width of the cerebellar granular layer at 3 months of age
|
• significant decrease in the width of the cerebellar molecular layer at 3 months of age
|
• progressive cerebellar atrophy with significant reduction in cerebellar size at 3 months of age
• however, cerebellar architecture is normal at 2-3 weeks of age
|
reproductive system
• young mice breed at a reduced frequency
