Caption: Gcn1em1(IMPC)J/Gcn1em1(IMPC)J embryos are small and growth delayed. E9.5 embryos remain unturned or display incomplete turning, show abnormal yolk sac vascularization, and abnormal head shape and cranial neural tube closure. E10.5 embryos display turning defects, severe cardiac defects, open cranial neural tube and more than 50% lethality. (details)
