What’s the difference between congenital myopathy and muscular dystrophy?

Muscular dystrophy is also a genetic condition that causes muscle weakness. However, there are several differences. With congenital myopathy, symptoms are present at birth or develop during infancy or childhood. With muscular dystrophy, some people have symptoms at birth, but others develop symptoms throughout childhood or adulthood.

With muscular dystrophy, the muscles tend to degenerate and regenerate. Muscular dystrophy is a progressive disease, which means symptoms may get worse over time. In addition, the heart and lungs are often affected over time. Lab tests can help distinguish the two diseases.
