• the cross-sectional area in the extensor digitorum longus is normal
• the number of fibers is increased in the soleus
• the fiber number in the extensor digitorum longus is normal
• the skeletal muscle exhibits less oxidative/slow fiber muscle type than wild-type

growth/size/body
• mice exhibit reduced body weight despite normal muscle weights for their size (27.0+/-1.0 g compared to 30.3+/-0.7 g in wild-type mice)
