hematopoietic system
• the hematocrit of 8 week old mice bearing the deletion in trans with the targeted allele is about 75% that of wild-type mice
• blood of 8 week old complex heterozygous mice has a hemoglobin (g/dl) content about 65% that of blood from wild-type mice
• red blood cells of 8 week old complex heterozygous mice contain only about 38% as much hemoglobin (pg) as RBCs of wild-type mice
• the hemoglobin concentration in red blood cells from 8 week old complex homozygotes is about 83% that of wild-type mice
• 8 week old complex heterozygotes have a mean RBC volume approximately 45% that of wild-type mice
• red blood cells of complex heterozygotes vary in shape and size
• the platelet count of 8 week old complex heterozygous mice is about 4.27 times that of wild-type mice
• reticulocytes of 8 week old complex heterozygous mice contain approximately half the cellular hemoglobin of those from wild-type mice
• in blood of 8 week old complex heterozygotes, both the absolute number and the proportion of reticulocytes are significantly elevated over those in blood of mice with at least one wild-type allele

homeostasis/metabolism
• the erythrocyte zinc-to-iron protoporphyrin IX ratio of 8 week old complex heterozygous mice is approximately 4.7-fold that of wild-type mice
• the liver iron content of complex heterozygotes is approximately 3-fold that of wild-type mice

liver/biliary system
• the liver iron content of complex heterozygotes is approximately 3-fold that of wild-type mice
