phenotype observed in females
phenotype observed in males
N normal phenotype
neoplasm
• homozygotes develop an abrupt onset, rapidly fatal acute leukemia with a median age of onset of 6 months and penetrance of over 90%
• median age of onset is earlier than in heterozygotes, however the leukemia phenotype and penetrance are the same as in heterozygous mutants

mortality/aging
• median survival is 473 days

hematopoietic system
• bone marrow cells exhibit increased replating efficiency as determined by increased colony formation compared with wild-type bone marrow
• mice exhibit an increase in Gr-1+ and Gr-1+/CD117+ cells in the spleen compared with wild-type mice
• mice exhibit an increase in Gr-1+ and Gr-1+/CD117+ cells in the spleen compared with wild-type mice

neoplasm
• most mice develop acute myeloid leukemia with promyelocytic features, including periperal leukocytosis and infiltration of the spleen and bone marrow with Gr-1+ CD117+ tumor cells unlike wild-type mice
• median tumor free survival is increased compared to in Ctsgtm3.1(PML/RARA)Ley heterozygotes

immune system
• mice exhibit an increase in Gr-1+ and Gr-1+/CD117+ cells in the spleen compared with wild-type mice
