N normal phenotype
mortality/aging
• fewer than expected mice are present at weaning with only a few mice dying after birth

behavior/neurological
N
• mice exhibit normal vertical exploratory activity (rearings)
• in the hole-board test, female mice exhibit increased number of unexplored squares and a tendency for defecation compared with control mice
• male, but not female, mice exhibit increased time in the open arms of a plus maze compared with control mice
• in a plus maze, mice exhibit fewer numbers of entry into the closed arms and reduced time in the center compared with control mice
• male, but not female, mice exhibit increased number of head dips and time spent dipping their head in the hole-board test compared with control mice
• decreased ambulation in the hole-board test, especially in female mice

growth/size/body
