N normal phenotype
mortality/aging
• fewer than expected mice are present after weaning
• defective mice die shortly after birth

reproductive system
• in female mice fed a folic acid deficient diet

embryo
• at E9.5, somite number varied between 6 and 22 indicating developmental delay
• in 30 of 37 mice from dams fed a folic acid-free diet
• craniofacial mesenchyme is less densely packed with fewer interconnections, increased extracellular space and more abundant clusters of blood cells compared with wild-type mice
• at the 21-somite stage, the inner surface of the neuroepithelium is convex and the edges of the neural folds are pointing towards the outside
• in 1 of 6 12-somite mice
• in the cranial neural tube of most mice at the 14-somite stage
• in 30% of mice from dams fed a folic acid-free diet unlike wild-type mice

craniofacial
• in some mice with increased cell death in the forehead spreading laterally and dorsally
• in some mice at E18.5

vision/eye
• at E18.5 in some mice

cellular
• increased cell death of craniofacial cells in the forehead spreading laterally and dorsally

growth/size/body
• in some mice at E18.5
• at E9.5, somite number varied between 6 and 22 indicating developmental delay
• in 30 of 37 mice from dams fed a folic acid-free diet
• craniofacial mesenchyme is less densely packed with fewer interconnections, increased extracellular space and more abundant clusters of blood cells compared with wild-type mice

nervous system
• at the 21-somite stage, the inner surface of the neuroepithelium is convex and the edges of the neural folds are pointing towards the outside
• in 1 of 6 12-somite mice
• in the cranial neural tube of most mice at the 14-somite stage
• in 30% of mice from dams fed a folic acid-free diet unlike wild-type mice
• in some mice at E18.5
