mortality/aging
• 2% of mice die within 2 to 4 months
• 11% of mice die three weeks after birth

hematopoietic system
• in affected mice
• the thymus weight to kidney weight or body weight in affected mice is decreased 0.21% to 0.32% of wild-type
• affected mice exhibit a 3.5-fold decrease in thymus cellularity due to a lack of lymphocytes emigrating from the marrow
• affected mice exhibit a depletion of immature cortical thymocytes (CD4+CD8+ double positive cells) compared to in wild-type mice
• affected mice exhibit a depletion of immature cortical thymocytes (CD4+CD8+ double positive cells) compared to in wild-type mice
• however, the number of CD4 and CD8 single positive cells is normal
• in affected mice erythroblasts are decreased to 50% of wild-type mice
• decreased by 45% in affected mice
• in the spleen of affected mice
• the spleen is discolored in affected mice
• affected mice exhibit poorly defined lymphatic nodules and severely decreased red pulp compared with wild-type mice
• lymphatic nodules of affected mice are smaller and less-organized with decreased internodular space compared to in wild-type mice
• in affected mice
• the spleen weight to kidney weight or body weight is decreased 0.12% to 0.16% of wild-type in affected mice
• 7.7-fold in affected mice

skeleton
N
• mice exhibit normal long bone growth and development
• 1% to 2% of mice exhibit tooth overgrowth
• affected mice exhibit a 14% decrease in the tibia growth plate width compared with wild-type mice
• affected mice exhibit an increase in waviness of the tibia growth plate unlike in wild-type mice
• affected mice exhibit more pronounced and somewhat variable tibia growth plate compared with wild-type mice
• more compressed than the hypertrophic zone in affected mice
• thoracicolumbar kyphosis in some mice
• neck lordosis in some mice
• 2 of 30 mice exhibit abnormal ossification of the second cervical vertebra characterized by malformed cartilage and an extra piece of bone in the neural arch region
• the marrow of affected mice is bright red and erythrocyte-filled unlike in wild-type mice
• the bone marrow of affected mice is depleted of leukocytes
• trabecular bony spicules of affected mice are slightly reduced in size and number compared to in wild-type mice

growth/size/body
