• ♀: phenotype observed in females
• ♂: phenotype observed in males
• N: normal phenotype

mortality/aging

decreased survivor rate ( J:133007 )

• 40% die before 5 weeks of age, probably as a result of issues relating to nursing

• mice surviving weaning have a normal life span

• cortical zonation is perturbed

abnormal adrenal gland zona fasciculata morphology ( J:133007 )

• numerous vacuolar structures

• large oil droplets develop

abnormal adrenal gland zona glomerulosa morphology ( J:133007 )

• numerous vacuolar structures

• large oil droplets develop

enlarged adrenal glands ( J:133007 )
