mortality/aging
postnatal lethality, incomplete penetrance ( J:84336 )
• normal at birth
• increased mortality at 2 to 4 weeks of age
• to about 20-30%
• gradual increase of global abnormalities

behavior/neurological
tremors ( J:84336 )
• severe tremors associated with movements

nervous system
nervous system phenotype ( J:84336 )
N
• no gross anatomic abnormalities seen in the CNS
• synaptic structures in the CA1 region appear normal
abnormal synaptic plasticity ( J:84336 )
• synaptic plasticity was greater
abnormal excitatory postsynaptic potential ( J:84336 )
• field excitatory postsynaptic potential was reduced to 10-20% of wild-type and was significantly lower than in Gria2 mutant homozygotes
enhanced long-term potentiation ( J:84336 )
• in the CA1 region
abnormal long-term depression ( J:84336 )
• in the CA1 region LTD is enhanced
• limited effect of D15 peptide in blocking LTD

growth/size/body
decreased body size ( J:84336 )
