♀	phenotype observed in females
♂	phenotype observed in males
N	normal phenotype

mortality/aging

decreased survivor rate ( J:47295 )

• only two thirds of expected female mice survive into adulthood

lethality throughout fetal growth and development, incomplete penetrance ( J:47295 )

• one third of female mice die after E15.5 of severe anemia

embryonic lethality during organogenesis, incomplete penetrance ( J:47295 )

• some female mice die between E11.5 and E14.5

hematopoietic system

abnormal definitive hematopoiesis ( J:47295 )

• at E15.5, most female mice exhibit an increase in circulating immature hematopoitic cells compared to in wild-type mice

anemia ( J:47295 )

• one third of female mice die after E15.5 of severe anemia

decreased erythrocyte cell number ( J:47295 )

• at E15.5, most female mice exhibit reduced total erythroid cells compared to in wild-type mice

embryo

pale yolk sac ( J:47295 )

• at E14.6 and E16.5

integument

pallor ( J:47295 )

• beyond E15.5, most female mice look pale

♀	phenotype observed in females
♂	phenotype observed in males
N	normal phenotype

mortality/aging

embryonic lethality during organogenesis, complete penetrance ( J:47295 )

• mice die by E13.5

hematopoietic system

abnormal erythropoiesis ( J:47295 )

• at E10.5, erythropoeisis is arrested at the proerythroblast stage and total cell numbers are 70% of wild-type

• however, erythroid development can be partially rescued in cultured ES cells

anemia ( J:47295 )

embryo

decreased embryo size ( J:47295 )

• at E11.5 to E12.5

pale yolk sac ( J:47295 )

• at E10.5, yolk sacs are pink instead of red as in wild-type mice

cardiovascular system

enlarged pericardium ( J:47295 )

• at E11.5 to E12.5

growth/size/body

decreased embryo size ( J:47295 )

• at E11.5 to E12.5

integument

pallor ( J:47295 )

• at E11.5 to E12.5, mice are pale
