mortality/aging
• most mice die around E10.5 and all mice are dead by E12.5

nervous system
• at E8.75, mice exhibit neuroectoderm that is splayed open with ectopic invaginations and an expanded floor plate unlike in wild-type mice
• however, dorso-lateral hinge points form
• expanded at E8.75
• 65% of mice display open neural tubes at 6 somite stage unlike wild-type mice

embryo
• 35% of mice display gastrulation defects characterized by abnormal posterior structures
• the anterior posterior axis is shortened and increased in width compared to in wild-type mice indicative of defective convergent extension movements
• at E8.75, mice exhibit neuroectoderm that is splayed open with ectopic invaginations and an expanded floor plate unlike in wild-type mice
• however, dorso-lateral hinge points form

mortality/aging
• fewer than expected mice are present 24 hours after birth (10% compared to the expected 25%)

nervous system
• at E14.5, 25% of mice exhibit neural tube defects including exencephaly and spina bifida unlike wild-type mice
• misorientation of cells is most pronounced in the outer hair cell layers with mispositioning of cells also observed
• misoriented outer hair cell are evident in apical and basal surfaces
• outer hair cells display abnormal cell shape and cell-cell contacts resulting in the appearance of pentagonal or heptagonal shaped cells instead of the hexagonal pattern observed in wild-type mice
• at E14.5, 25% of mice exhibit neural tube defects including exencephaly and spina bifida unlike wild-type mice
