mortality/aging
• mice have a short lifespan dying by 10 months of age
• fewer mice than expected are obtained (no time point for lethality given)
• however, postnatal lethality can be partially rescued by supplementing food with porridge

reproductive system

neoplasm
• after 10 months, mice develop benign and malignant Schwann cell tumors

craniofacial
• at P17 and P19, molar eruption is retarded or absent
• at P17 and P19, molar eruption is retarded or absent

nervous system
• 2 of 4 mice and 4 months and 1 mouse at P17 exhibit hyperplasia or hypertrophy in Schwann cells of distal peripheral nerves
• at P19 and P33, Schwann cells are without a clear relation with an axon and many of the myelin sheaths herniated and loop into the central axonal region unlike in wild-type mice

growth/size/body
• at P17 and P19, molar eruption is retarded or absent
• at P17 and P19, molar eruption is retarded or absent

hearing/vestibular/ear

immune system

skeleton
• at P17 and P19, molar eruption is retarded or absent
• at P17 and P19, molar eruption is retarded or absent
