hematopoietic system
N
• 16-18-month old animals show similar ertythrocyte counts, hematocrits, hemoglobin concentrations, mean corpuscular volumes, and total leukocyte counts to wild-type mice (J:132542)
• variably increased erythropoiesis is detected in the bone marrow
• reticulocyte counts are significantly increased (about 4-fold) compared to wild-type
• phenotype consistent with compensated hemolytic anemia is observed
• increased iron deposits are observed in spleen
• splenomegaly is variable with mice having spleens of normal size up to 5 times normal size
• mice show elevated hemolysis

homeostasis/metabolism
• increased iron deposits are observed in spleen
• haptoglobin levels are reduced 10-fold compared to wild-type
• total porphyrin I isomer levels are greater greater in erythrocytes, plasma, urine, liver, and feces
• loading with 5-aminolevulinic acid (ALA), plasma porphyrin I isomer levels increase immediately 2- to 3-fold higher than in untreated mutant mice (10-fold higher than wild-type)
• hepatic, splenic and erythrocytic uroporphyrinogen III synthase (URO-synthase) activity is greatly reduced compared to wild-type

immune system
• increased iron deposits are observed in spleen
• splenomegaly is variable with mice having spleens of normal size up to 5 times normal size
