Summary

Story summary

Congenital myopathies are genetically diverse neuromuscular disorders marked by early hypotonia and muscle weakness.
Satellite cell dysfunction is implicated in these conditions.
The review examines four genes—PAX7, MYOD1, MEGF10, and MYMK.
PAX7 mutations are linked to progressive congenital myopathy and scoliosis.
MYOD1 variants disrupt myogenic differentiation, MEGF10 loss-of-function variants cause severe early-onset myopathy, and MYMK mutations produce facial and axial weakness.
