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

embryo
• at E14.5, 25% of mice exhibit neural tube defects including exencephaly and spina bifida unlike wild-type mice

limbs/digits/tail
• occasionally looped

hearing/vestibular/ear
• 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
