Living with Congenital myopathy

A group of genetic muscle conditions, usually noticed at birth, that cause weakness and low muscle tone.

Understanding Congenital myopathy

Congenital myopathy is a term for genetic muscle conditions that are usually noticed at birth and cause weakness and low muscle tone.

Some types do not show symptoms until infancy or childhood. There are many types, and they vary in severity. Some symptoms stay stable and others progress slowly. Symptoms may include weak muscles, trouble breathing or eating, slowly reaching developmental goals, delayed movement skills, and a curved spine.
