• N: normal phenotype

hematopoietic system

enlarged spleen ( J:244493 )

microcytic anemia ( J:244493 )

hypochromic microcytic anemia ( J:244493 )

• microcytic hypochromic red cells and abundant target cells

increased erythroblast number ( J:244493 )

• increase in early erythroblast expansion in the spleen

• however, reticulocyte counts and red cell half-life are normal and white cell counts are normal

abnormal erythrocyte morphology ( J:244493 )

• whole blood heme in red cells is reduced

decreased mean corpuscular volume ( J:244493 )

increased red blood cell distribution width ( J:244493 )

increased spleen red pulp amount ( J:244493 )

homeostasis/metabolism

increased circulating ferritin level ( J:244493 )

porphyria ( J:244493 )

♀ • 3- to 4-fold increase in porphyrins, particularly coproporphyrinogen III, in the urine and feces in females, but not males

♀ • the ratio of the two coproporphyrinogen isomers (CIII:CI) is elevated in the feces of females

♀ • however, urinary porphobilinogen level is normal

♀ • females treated with phenobarbital to induce porphyric stress exhibit elevated fecal coproporphyrinogen III levels and elevation in the CIII:CI ratio, however, urinary prophyrins are not significantly increased above baseline levels

♀ • females fasted for 15 hours do not exhibit clinical crisis and mice remain well and urinary prophyrins do not increase

immune system

enlarged spleen ( J:244493 )

increased spleen red pulp amount ( J:244493 )

growth/size/body

enlarged spleen ( J:244493 )
