♀ phenotype observed in females
♂ phenotype observed in males
N normal phenotype
mortality/aging
premature death ( J:100997 )
• lifespan of mice is at least 2 years of age compared to mice homozygous for a null allele of Ptf1a that die shortly after birth

nervous system
abnormal Purkinje cell differentiation ( J:100997 )
• purkinje cells fail to develop
thin external granule cell layer ( J:100997 )
• the EGL is much thinner at 4 days after birth compared to age-matched controls
• the EGL continues to thin with development from apoptosis until it disappears by 2 weeks after birth
abnormal inferior olivary complex morphology ( J:100997 )
• the inferior olivary nucleus and the pontine nuclei are absent in adults
• both structures are present at birth but regress 4 days later and disappear by 6 days after birth due to apoptosis
absent cerebellar lobules ( J:100997 )
• a small cerebellum without lobules is present in mice at postnatal day 4
absent cerebellum ( J:100997 )
• adults lack all cerebellar cortical layers
abnormal GABAergic neuron morphology ( J:100997 )
• GABA neurons fail to develop in the cerebellar ventricular zone
abnormal glutaminergic neuron morphology ( J:100997 )
• within the cerebellum rudiment, there are 2.3 fold less glutaminergic neurons compared to similar area in wild-type brain

behavior/neurological
tremors ( J:100997 )
• is observed in adults
ataxia ( J:100997 )
• occurs in adults
impaired coordination ( J:100997 )
• uncoordinated locomotion is observed in adults

growth/size/body
decreased body size ( J:100997 )
• body sizes are generally smaller than littermate controls

cellular
abnormal Purkinje cell differentiation ( J:100997 )
• purkinje cells fail to develop

nervous system
abnormal Purkinje cell differentiation ( J:100997 )
• purkinje cells fail to develop similar to CbllTg(Alb-KL)7-2Mhos homozygotes
abnormal GABAergic neuron morphology ( J:100997 )
• failure of GABA neurons to develop by 4 days after birth is similar to CbllTg(Alb-KL)7-2Mhos homozygotes

cellular
abnormal Purkinje cell differentiation ( J:100997 )
• purkinje cells fail to develop similar to CbllTg(Alb-KL)7-2Mhos homozygotes
