mortality/aging
• fewer than expected mice are present at weaning

reproductive system

skeleton
• in some mice with the T12 phenotype
• mice exhibit a T13/L5 (jn most mice) or T12/L6 (in some mice) configuration compared with T13/L6 (in most) or T13/L5 (in few) wild-type mice
• T10, T11 and T12 in some mice exhibit high incidence of fissures affecting the dorsal surface
• T13 to a lumbar vertebrae
• missing sixth lumbar vertebrae
• in some E15 and adult mice
• fusion of all sacral vertebrae
• reduced migration
• however, proliferation is normal
