mortality/aging
• survival is on average 22 weeks

neoplasm
• mutants develop multiple visible subcutaneous tumors with 100% penetrance, starting from 4 months of age
• majority of tumors are located on the back and sides
• each mutant has more than one lesion with features of human neurofibroma and malignant peripheral nerve sheath tumor
• progressive development of malignant peripheral nerve sheath tumors (MPNST) from neurofibroma, with 100% of mutants showing MPNST when followed for 7 months
• Pten loss of heterozygosity in mutants correlates with MPNST transformation from neurofibromas

nervous system
• each mutant has more than one lesion with features of human neurofibroma and malignant peripheral nerve sheath tumor
• progressive development of malignant peripheral nerve sheath tumors (MPNST) from neurofibroma, with 100% of mutants showing MPNST when followed for 7 months
• Pten loss of heterozygosity in mutants correlates with MPNST transformation from neurofibromas
