|
• 11% of mice die three weeks after birth

hematopoietic system
small thymus
(
J:62230
)
• 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
|
• in affected 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
|
• in 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
|
small spleen
(
J:62230
)
• 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
|

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
|
• 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
• 1% to 2% of mice exhibit tooth overgrowth
|
• affected mice exhibit dwarfism and weight one third as much as wild-type mice
• however, mice that survive beyond weaning recover
|
behavior/neurological
craniofacial
• 1% to 2% of mice exhibit tooth overgrowth
