mortality/aging
• 1 week after birth, mice are dead

nervous system
• mice exhibit impaired development of retrotapezoid nucleus neurons compared with wild-type mice
• the parafacial area e-pF oscillator exhibits only occasional motor activity bursts with reduced frequency compared to in wild-type mice
• rhythmic phrenic discharges are less frequent than in wild-type mice
• mice fail to exhibit an accelerated respiratory-like rhythm phrenic discharge in response to low pH challenge unlike similarly treated wild-type mice

cellular
• mice exhibit impaired development of retrotapezoid nucleus neurons compared with wild-type mice
