phenotype observed in females
phenotype observed in males
N normal phenotype
• females appear normal for the first 4 months but show ataxic gait at later ages
• females appear normal for the first 4 months but show hypoactivity at later ages

• females appear normal for the first 4 months but gain weight at later ages

respiratory system
• mutants at 10 weeks of age exhibit an abnormally high breathing frequency associated with marked decreases in expiratory time and total breath duration and a small but significant decrease in inspiratory time
• treatment with LM22A-4, a small molecule BDNF loop domain mimetic that acts as a selective TrkB agonist, improves the respiratory function of mutants
• breathing dysfunction is characterized by increased frequency due to periods of tachypnea and increased apneas
• 20% of mutants exhibit apneas at 8 weeks of age and by 12 weeks of age, 50% of mutants exhibit apneas
• number of apneas increases between 8 and 12 weeks of age in mutants
