N normal phenotype
mortality/aging

nervous system
• 88.8% exhibit a neural tube defect
• seen in some mutants
• caudal rachischisis in all mutants
• mutants sometimes show exencephaly and spina bifida or exencephaly and a curly tail
• in 15 and 16 day old embryos, spinal gangalia of the lumbosacral region were reduced in size, residual or missing
• this phenotype is less severe than seen in Pax3Sp mutants
• dorsal roots are more disorganized and appear less frequently than in wild-type

limbs/digits/tail
• seen in some mutants

embryo
• 88.8% exhibit a neural tube defect
• seen in some mutants
• caudal rachischisis in all mutants
