phenotype observed in females
phenotype observed in males
N normal phenotype
• 8 week old females show a significant decrease in preference for interacting with a stimulus mouse in a social approach assay, with mice spending significantly less time interacting with the stimulus mouse than in wild-type mice or either single heterozygote, indicating impaired social approach behavior in females
• while 8 week old males do not show a change in preference for social interaction for the first trial, upon reexposure to the same social target in trial 2, males do not show attenuation of preference for social investigation between the first and second trials as seen in wild-type mice, indicating impaired social recognition in males

nervous system
• deficits in prepulse inhibition of the acoustic startle response indicate impaired sensorimotor gating
• mice show deficits in prepulse inhibition of the acoustic startle response to a similar level as single Pten heterozygotes
• however, mice respond to the olfactory-habituation-dishabituation test normally, indicating normal olfactory function

• macrocephaly that is more severe than in either single heterozygote
