N normal phenotype
behavior/neurological
decreased grip strength ( J:337175 )
• at 3 months of age, mice show a decrease in the latency time (s) to fall from an inverted screen that is similar to that in single Stmn2em1Jmi homozygotes, indicating severe motor function impairment

nervous system
abnormal neuromuscular synapse morphology ( J:337175 )
• lumbrical muscle NMJs exhibit presynaptic and postsynaptic elements that are indistinguishable from those of single Stmn2em1Jmi homozygotes, including endplate fragmentation and many regions of partial innervation
