Congenital Myopathies

Congenital myopathies are a rare group of genetic neuromuscular diseases that are present at birth. In most cases, the cause is unknown. Symptoms typically include muscle weakness, stiffness, and joint contractures, as well as hypotonia, which can cause developmental delays. Other common features may include scoliosis, respiratory problems, swallowing difficulties, and cardiac issues. Diagnosis is often challenging as there are currently no laboratory tests or tools that can pinpoint congenital myopathies. Diagnosis often requires a combination of examinations, including physical, neurological, and musculoskeletal evaluations, as well as electrodiagnostic tests, medical imaging, and a muscle biopsy. Treatment for congenital myopathies is focused on managing symptoms and improving quality of life. It may involve physical therapy, occupational therapy, assistive devices, medications, and surgery, depending on the individual’s needs. As there is no cure, treatment plans focus on management and prevention of further complications. Although often rare, congenital myopathies can be life-threatening. Early and accurate diagnosis is critical for providing the best care possible. Fortunately, research such as whole-exome sequencing is making it possible to diagnose these conditions faster and with more accuracy. With improved diagnosis and treatment options, the quality of life for people living with congenital myopathies is improving.
