phenotype observed in females
phenotype observed in males
N normal phenotype
behavior/neurological
• males show lower acoustic startle response
• some mice exhibit tremor, abnormal gait, and less tail elevation
• mice exhibit reduction of 2-paw strength
• some mice exhibit abnormal gait
• mice exhibit hypoalgesia in the hot plate test

hematopoietic system
• males exhibit slightly higher frequency of CD19+ cells

immune system
• mice exhibit a higher proportion of CD44 expressing cells and lower proportion of CD62L within the T cell cluster
• males exhibit slightly higher frequency of CD19+ cells

nervous system

respiratory system
• females show slightly lower respiratory rates, slightly lower tidal volumes and minute ventilation volumes at rest
• however, mice show normal adaptation to activity
• females show slightly lower minute ventilation volumes at rest

reproductive system
N
• mice are fertile

mortality/aging
N
• mice are viable, are obtained in the expected Mendelian ratio and have a lifespan of 15-17 months
