phenotype observed in females
phenotype observed in males
N normal phenotype
mortality/aging
• mutants surviving past the first day die between 4 and 25 days of age
• most mutants die during the first postnatal day

growth/size/body
• homozygotes are smaller in size than littermates
• mutants surviving past the first day exhibit progressive growth retardation until time of death

behavior/neurological
• mutants are unable to feed normally, as their stomachs lacked milk and were filled with air
• mutants exhibit abnormal limb posturing
• mutants exhibit a low level of activity after birth
• surviving mutants exhibit decreased motor activity with time until death between 4 and 25 days of age

nervous system
• at 13.5 all parasympathetic ganglia of the head are missing
• visceromotor neurons project abnormally in the facial nerve
• in E10.5 embryos a subtle increase in the number of dI3 and dI5 neurons is seen
• but, no significant changes in the number of dI2 and dI4/6 neurons is detected
• neuronal differentiation is absent or abnormal in this ganglion
• neuronal differentiation is absent or abnormal in this ganglion
• neither the corda tympani nor the greater superficial petrosal nerve have formed at E11.5
• mice show a transient defect in neurogenesis in populations of sensory neurons in the DRGs
