• in the contextual fear conditioning test, mice freeze for similar amounts of time as wild-type mice on day 1 of the test, indicating no impairment in contextual fear learning, however mice show altered memory extinction on day 2, spending more time freezing
• P6 pups take more time to right themselves than wild-type pups in a surface-righting test
• mice show decreased acoustic startle response
• females, but not males, show a small, but significant decrease in forelimb grip strength at 13 weeks of age

growth/size/body
• P6 pups weigh less than wild-type pups

hearing/vestibular/ear
• 9-week-old mice show an auditory brainstem response (ABR) threshold increase at low frequency stimulation (4 and 8 kHz)

• however, no gross abnormalities in the organ of Corti at E18 and P2 are seen and there is no change in distortion product otoacoustic emission threshold
• mice display hearing defects

muscle
• increase in righting time and decreased grip strength suggests neonatal hypotonia
