muscle
• increase in type IIB fibers in the gastrocnemius muscle of mice with maternally inherited mutant allele
• type IIB fibers in the gastrocnemius muscle of mice with maternally inherited mutant allele are enriched in large fibers unlike wild-type mice
• fast-twitch muscle hypertrophy is seen in the gastrocnemius, tibialis anterior, and gluteus maximus muscles at P10 but not in mice over 3 weeks of age with a maternally inherited mutant allele
• however, the soleus muscle (slow-twitch muscle) is slightly smaller in neonatal mice with a maternally inherited mutant allele
• muscle mass is similar to wild-type controls in mice with a paternally inherited mutant allele

cellular
• the paternal allele is functionally inactivated
