mortality/aging

preweaning lethality, incomplete penetrance ( J:203277 )

• fewer than expected mice are present at weaning

reproductive system

reduced female fertility ( J:203277 )

reduced male fertility ( J:203277 )

skeleton

decreased rib number ( J:203277 )

• in some mice with the T12 phenotype

abnormal vertebrae morphology ( J:203277 )

• 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

abnormal thoracic vertebrae morphology ( J:203277 )

• T10, T11 and T12 in some mice exhibit high incidence of fissures affecting the dorsal surface

thoracic vertebral transformation ( J:203277 )
