behavior/neurological
• homozygous mice spend less time exploring open arms in the elevated plus-maze test
|
• mice demonstrate increased tendency to stay at the sides of an open field box and spent less time in active locomotion or rearing activity
|
• increased mean latency in jumping response in the hot-plate test, but no difference in the tail-flick test
|
• males do not initiate copulatory behavior
|
endocrine/exocrine glands
• appear vacuolated
|
• degeneration noted with age
|
small testis

growth/size/body
• the body weight of homozygous animals at 7 weeks of age are approximately 70% of controls
|
homeostasis/metabolism
