Find Mice Using the International Mouse Strain Resource (IMSR)
Mouse lines carrying:
Shank3tm1.2Bux mutation (1 available); any Shank3 mutation (31 available)
phenotype observed in females
phenotype observed in males
N normal phenotype
mortality/aging
• fewer than expected homozygotes (16.22%) were produced from a heterozygote x heterozygote cross
• Background Sensitivity: homozygote lethality is background dependent, the greatest loss is observed on the 129S6 background, followed by FVB/N and C57BL/6

behavior/neurological
N
• Background Sensitivity: tail flick latency is observed in mice on the C57BL/6 background, but not on FVB/N or 129S6/SvEvTac backgrounds
• decreased freezing is observed following 3 tone-shock associations and after third association, however no significant differences are observed in contextual or cued conditioning tests
• open arc entries are increased in elevated zero-maze as compared to littermate controls
• mice exhibit decrease in mean forelimb grip strength as compared to littermate controls
• mice exhibit hyperactivity in first 10 minutes of open field test, but return to activity level similar to controls

growth/size/body
• mice exhibit lower body weight than controls

phenotype observed in females
phenotype observed in males
N normal phenotype
mortality/aging
• fewer than expected homozygotes (21%) were produced from a heterozygote x heterozygote cross
• Background Sensitivity: homozygote lethality is background dependent, the greatest loss is observed on the 129S6 background, followed by FVB/N and C57BL/6

behavior/neurological
• mice are more active in elevated zero maze as determined by increases in total moving distance and total moving time
• open arc entries are increased in elevated zero-maze
• homozygous mice exhibit a preference for the unfamiliar mouse over the familiar mouse relative to littermate controls
• Background Sensitivity: mice exhibit a longer tail flick latency in the first trial of the tail-flick assay for pain sensitivity as compared to littermate controls and mice on the FVB/N and 129S6/SvEvTac backgrounds
• mice exhibit a lower latency to start crossing and spent a shorter time crossing in beam walking test as compared to littermate controls
• decreased number of rears in open field test as compared to littermate controls
• mice travel less in center of the open field test during first 10 minutes of test
