hm1

• Allelic Composition: Tmprss9^tm1.3Hzo/Tmprss9^tm1.3Hzo
• Genetic Background: involves: 129S1/Sv * C57BL/6J * C57BL/6NTac

• ♀: phenotype observed in females
• ♂: phenotype observed in males
• N: normal phenotype

behavior/neurological

abnormal object recognition memory ( J:284914 )

♀ • 1-year-old females show borderline deficits in the discrimination between novel and familiar objects, indicating minor recognition memory deficits

♀ • however, males and younger females show normal novel object recognition and mice exhibit normal fear memory in contextual and cued fear conditioning

increased thermal nociceptive threshold ( J:284914 )

♀ • 16-week-old females exhibit delayed pain response in the hot plate test

♀ • however, males and females at other ages do not exhibit nociception defects

abnormal social investigation ( J:284914 )

• in the 3-chamber interaction test, no difference is seen in the interaction time with the novel mouse versus an inanimate object compared to wild-type mice that show increased interaction with the novel mouse than the inanimate object in 13-week-old and 1-year-old mice

• however, mice do not exhibit repetitive behaviors, anxiety-like behaviors, motor learning and coordination deficits, or sensorimotor gating abnormalities

abnormal social recognition ( J:284914 )

• in the partition test, mice (females at 13 weeks and 1 year of age and males at 1 year of age) spend less time interacting with a novel mouse that replaces the familiar mouse than controls

growth/size/body

increased body weight ( J:284914 )

♀ • females, but not males, are heavier at 20 and 22 weeks but not at other time points from 3 to 26 weeks of age

nervous system

nervous system phenotype ( J:284914 )

N • no differences in overall brain cytoarchitecture are seen and in neuronal density in the hippocampus, cerebellum, and amygdala
