Allelic Composition Genetic Background
Atp1b1em1(IMPC)Mbp/Atp1b1em1(IMPC)Mbp embryos show growth retardation, abnormal embryo turning at E9.5, abnormal head shape, a slight kink in their caudal neural tube and defect in cranial neural tube closure, abnormal heart, and half show branchial arch defects.Atp1b1em1(IMPC)Mbp/Atp1b1em1(IMPC)MbpC57BL/6NCrl-Atp1b1em1(IMPC)Mbp/Mmucd
AlleleSymbol(MGI:7425530|0)/Atp1b1em1(IMPC)Mbp embryos exhibit normal placentas.Atp1b1em1(IMPC)Mbp/Atp1b1em1(IMPC)MbpC57BL/6NCrl-Atp1b1em1(IMPC)Mbp/Mmucd
E8.5 Atp1b1em1(IMPC)Mbp/Atp1b1em1(IMPC)Mbp embryos that are smaller than litter mates (but not grossly abnormal which represent a minority) have normal germ layer patterning.Atp1b1em1(IMPC)Mbp/Atp1b1em1(IMPC)MbpC57BL/6NCrl-Atp1b1em1(IMPC)Mbp/Mmucd
