mortality/aging
• mutants survive until midgestation but then die as a result of severe anemia; lethality begins at E11.5 and all mutants are dead by E14.5

hematopoietic system
• in Smarca1enu1/Smarcatm1Mag mutants, the developmental switch of erythropoiesis from the yolk sac to the fetal liver around E10.5 does not occur properly and yolk sac-derived erythrocytes persist for several days
• At E12.5, mutants still alive showed greatly diminished erythropoiesis in the fetal liver
• mutants have proerythroblasts and basophilic erythroblasts but lack mature polychromatic erythroblasts, orthochromatic erythroblasts and enucleated reticulocytes

liver/biliary system
• mutant fetal livers have a red speckled appearance or are completely pale
