mortality/aging

perinatal lethality, complete penetrance ( J:238 )

• survive to birth

nervous system

abnormal neural tube morphology ( J:70476 )

• 88.8% exhibit a neural tube defect

spina bifida ( J:70476 )

• seen in some mutants

caudal rachischisis ( J:238 )

• caudal rachischisis in all mutants

exencephaly ( J:70476 )

• mutants sometimes show exencephaly and spina bifida or exencephaly and a curly tail

abnormal dorsal root ganglion morphology ( J:70476 )

• 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 Pax3^Sp mutants

disorganized dorsal root ganglion ( J:70476 )

• dorsal roots are more disorganized and appear less frequently than in wild-type

limbs/digits/tail

curly tail ( J:70476 )

• seen in some mutants

embryo

abnormal neural tube morphology ( J:70476 )

• 88.8% exhibit a neural tube defect

spina bifida ( J:70476 )

• seen in some mutants

caudal rachischisis ( J:238 )

• caudal rachischisis in all mutants
