N normal phenotype
behavior/neurological
N
• despite locomotor deficits, mice exhibit normal balance, coordination and anxiety levels
• mice exhibit reduced learning of active avoidance behaviors in a T-maze test compared to wild-type mice
• in a T-maze mice exhibit longer avoidance time than wild-type mice
• mice perform worse than wild-type mice in a passive avoidance T-maze test and exhibit increased time to make the incorrect response compared to wild-type mice
• mice fail to exhibit an increase in locomotor activity when exposed to a novel environment
• when exposed to a male intruder, male mice initiate fewer attacks and exhibit increased latency to attack compared to wild-type mice
• however, serotonine and dopamine levels are normal
• mice exhibit reduced grip strength compared to wild-type mice
• mice exhibit reduced locomotion in new and familiar environments compared to wild-type mice

nervous system
N
• mice exhibit normal brain morphology and levels of serotonine and dopamine are normal
• neurons have smaller growth cones with reduced widths compare to wild-type growth cones and they extend along the shaft unlike growth cones
• young and old cultured neurons have fewer, shorter neurites than wild-type neurons

reproductive system
N
• mice are fertile and male mice exhibit normal testes morphology
