mortality/aging
• median lifespan of 85 days

growth/size/body
• at 8 weeks of age
• weight gain starts at 7 weeks of age and is more gradual than in mutant mice not carrying the transgene

nervous system
• brain weight peaks at 7 weeks (1 week earlier than in controls) then declines
• brain weight peaks at 7 weeks (1 week earlier than in controls) then declines
• decrease in the number of ATRX containing foci at 7 weeks of age and only a few foci are detected at 9 weeks of age
• decrease in the number of ATRX containing foci at 7 weeks of age and only a few foci are detected at 9 weeks of age

behavior/neurological
• at all ages tested and severity increases with age
• severity is reduced compared to mutant mice not carrying the transgene
• at all ages tested and severity increases with age
• severity is reduced compared to mutant mice not carrying the transgene
