N normal phenotype
• mice exhibit normal general exploratory behavior
• increased amphetamine-induced locomotor activity during the first ten minutes of habituation
• reduced nest building scores at 5 h but not 24 h indicating autism-like behavior
• however, mice exhibit normal performance in a sucrose preference test
• reduced immobility in a tail suspension or forced swim test
• reduced exploration of open arms and higher latency to enter open arms in an elevated plus maze
• however, a trend toward increased novelty-induced hypophagia is not significant
• reduced exploration of and increased distance from a novel object
• however, mice exhibit normal novel object recognition
• mice spend less time investigating a novel social partner and novel social odors compared with wild-type mice
• however, mice exhibit a normal preference for a novel social partner
• after object presentation
• higher latency to fall on a rotarod only on the first day of testing
• only on the first day of testing
• mice spend less time investigating and preference for a social partner compared with wild-type mice
