mortality/aging
• double mutants survive an average of 210 days, with many living more than 1 year
• lifespan is less than that of Smn1tm1Msd heterozygotes
|
muscle
• muscle fiber distribution is different from normal muscle; mice have a greater number of smaller diameter fibers relative to controls
|
nervous system
N |
• mice have normal motor neuron counts and lumbar root counts, compared to triple homozygotes for Smn1tm1Msd, Tg(ACTA1-SMN)63Ahmb, and Tg(SMN2)89Ahmb
