embryo
• at E12.5, homozygotes exhibit successful septation of the distal outflow tract; however, the number of NCCs contributing to the proximal outflow tract is significantly reduced
• at E9.5, cardiac NCCs migrate to the developing caudal pharyngeal arches of mutant embryos in numbers comparable to those of wild-type embryos; however, at E11.5, NCCs fail to invaginate on the right side of the proximal aortic sac at the level of its connection with the 6th aortic arch arteries
• as a result, the conotruncal cushions remain oriented laterally relative to one another

cardiovascular system
• at E12.5, homozygotes exhibit successful septation of the distal outflow tract; however, the number of NCCs contributing to the proximal outflow tract is significantly reduced
• homozygotes exhibit abnormal NCC behavior during outflow tract remodeling

nervous system
• at E12.5, homozygotes exhibit successful septation of the distal outflow tract; however, the number of NCCs contributing to the proximal outflow tract is significantly reduced
