Main Results:

  • Skeletal muscle formation is precisely controlled by intricate molecular signaling.
  • Disruptions in these pathways lead to hereditary congenital skeletal muscle defects.
  • Knowledge of developmental mechanisms is crucial for understanding disease etiology.

Conclusions:

  • Comprehensive understanding of skeletal muscle development is essential.
  • This knowledge aids in improving diagnostic and therapeutic strategies for congenital muscle diseases.
