N normal phenotype
behavior/neurological
• mutants begin to exhibit spontaneous partial motor seizures and generalized tonic-clonic seizures at P16
• general seizures last 45-100 seconds, during which time mice experience repetitive jerking of all four limbs and neck, running, and jumping, and tail clonus; seizures often end with tonic hindlimb extension, indicative of a severe seizure
• mutants begin to exhibit generalized tonic-clonic seizures at P16

mortality/aging
• sporadic death begins to occur at P16, with 100% mortality by P24

nervous system
• mutants begin to exhibit spontaneous partial motor seizures and generalized tonic-clonic seizures at P16
• general seizures last 45-100 seconds, during which time mice experience repetitive jerking of all four limbs and neck, running, and jumping, and tail clonus; seizures often end with tonic hindlimb extension, indicative of a severe seizure
• mutants begin to exhibit generalized tonic-clonic seizures at P16
