nervous system
• at E14.5, mice exhibit microform holoprosencephaly

craniofacial
• at E14.5, mice show a higher cell packing index (CPI, a measure of cell density) within the palatal shelf mesenchymal component than double heterozygous controls
• at E14.5, mice also show a higher proliferation index per unit area (PIPUA) within palatal shelf mesenchyme than double heterozygous controls, but to a lesser extent than in Boctm1Aok homozygotes (which have the lowest CPI and highest PIPUA value amongst genotypes)
• at E14.5, TUNEL assays showed lower levels of apoptosis within anterior, medial and posterior sections of the palatal shelves than in double heterozygous controls
• at E14.5, mice exhibit cleft palate with incomplete penetrance

digestive/alimentary system
• at E14.5, mice show a higher cell packing index (CPI, a measure of cell density) within the palatal shelf mesenchymal component than double heterozygous controls
