Developmental defects in Smg1Gt(RRT449)Byg/Smg1Gt(RRT449)Byg embryos

mortality/aging
• mice are present in utero until E12.5

cardiovascular system
• no vascular system develops
• at E8.0, mice lack a developed heart field
• delayed at E10.5 without heart looping and development of a multi-chambered heart structure
• in the thoracoabdominal region at E12.5

embryo
• unturned at E8.0
• delayed turning by E10.5
• at E8.0 and E10.5

nervous system
• at E10.5 without formation of the three primary brain vesicles

vision/eye

cellular
• embryonic cells accumulate premature termination codon-containing splice variant transcripts from 9% of genes predicted to contain alternative splicing events capable of eliciting nonsense-mediated mRNA decay
• in embryos at E12.5

growth/size/body
• at E8.0 and E10.5

craniofacial
• at E8.0, mice lack an optic pit indentation
