• N: normal phenotype

mortality/aging

premature death ( J:199542 )

• mutants have a median survival of 127 days of age

neoplasm

increased metastatic potential ( J:199542 )

• 20.6% of mice show metastatic dissemination, commonly to the lung and liver

increased hibernoma incidence ( J:199542 )

• seen in one mutant

increased osteosarcoma incidence ( J:199542 )

• mutants develop osteosarcoma with a mean latency of 127 days

• 64.7% of tumors are found in the mandible/head, 11.8% of tumors are found on the lower long bones, and 23.5% of tumors are in other axial locations

• osteosarcoma is characterized by predominant areas of fibroblastic (undifferentiated) morphology accompanied by intermittent areas of mineralized osteoid resembling human fibroblastic/undifferentiated osteosarcoma
