N normal phenotype
hematopoietic system
• exhibit a minor but significant degree of erythropenia
• iron deficiency in the spleen

homeostasis/metabolism
• duodenal and hepatic iron accumulation is associated with increased ferritin L-chain expression and splenic iron deficiency is associated with decreased ferritin L-chain expression, however no differences in trans-ferrin staturation values
• iron loading of the duodenum
• however, no difference is seen in serum iron levels
• iron deficiency in the spleen
• increase in iron content in the liver

digestive/alimentary system
• iron loading of the duodenum
• however, no difference is seen in serum iron levels
• increase in iron content in the duodenum

immune system
• iron deficiency in the spleen

behavior/neurological
• locomotion is mildly affected, however do not display the neurodegenerative disorder seen in homozygous Ireb2tm1Roua mice

liver/biliary system
• increase in iron content in the liver
