mortality/aging
• death occurred around the 1st week of age

growth/size/body
• although of normal size at birth, homozygotes became noticeably smaller than normal by 3-4 days of age
• by 7 days of age homozygotes were severely runted (1/3 normal weight)

hematopoietic system
• elevated numbers of granulocyte precursors in bone marrow and spleen as animals age
• atrophy in mice over 6 days of age
• 3 fold increase in peripheral WBC count - about 95% neutrophils
• small size by day 2 with a worsening size reduction until death

immune system
• elevated numbers of granulocyte precursors in bone marrow and spleen as animals age
• atrophy in mice over 6 days of age
• 3 fold increase in peripheral WBC count - about 95% neutrophils

integument
• poorly defined basal layer
• significant sloughing

cellular
• elevated numbers of granulocyte precursors in bone marrow and spleen as animals age
