What is congenital myopathy?

Congenital myopathy is a rare genetic disorder affecting muscle strength. Congenital simply means "existing at birth," and myopathy refers to "disease of muscle." Infants born with congenital myopathies have no muscle tone. Other symptoms include skeletal malformations, weak or poorly aligned bones, feeding difficulties, and breathing problems. In some cases, symptoms begin at birth or in infancy and continue into childhood.

What are the different types of congenital myopathy?

There are six major types of congenital myopathy, but several other rare forms have also been identified. Each type has differences in symptoms, severity, treatment options, and outlook.

There are six main types of congenital myopathy, including:

  • Central core disease
  • Minicore (multicore) disease
  • Nemaline myopathy
  • Centronuclear myopathy
  • Myotubular myopathy
  • Congenital fibre-type disproportion myopathy
  • a

What are the symptoms of congenital myopathy?

Depending on the variety, symptoms of the condition can present at birth or develop throughout infancy and childhood. The most common symptoms of the congenital myopathy include:

  • Floppiness (hypotonia): Loss of muscle tone that progressively worsens over time in your child.
  • Muscle weakness: The neck, shoulders, and pelvis are those muscles that are commonly affected.
  • Difficulty breathing: You are breathless or feel that you cannot breathe air into your lungs because of the weakness of breathing muscles.
  • Developmental delays: You fail to meet certain developmental milestones such as sitting up or turning over.
  • Problems with feeding: Chewing, drinking, eating with a spoon, and sucking from a breast or bottle can all be unusual and challenging.
  • Falling/stumbling: Muscle weakness can lead toddlers to fall or stumble. 

What causes congenital myopathy?

Most congenital myopathies are caused by changes (mutations) in specific genes. These alterationsad to issues with your child's brain, muscles, and the nerves that control thethosescles.

How is congenital myopathy diagnosed?

The healthcare provider of your child at birth usually constitutes a neonatologist or a paediatrician and conducts a physical examination that can diagnose congenital myopathy. Such medical professionals may recommend you to a neurologist and most likely a geneticist after requesting a number of tests to confirm the diagnosis. Among the tests are:

  • Blood test: A blood test can detect elevated levels of creatine kinase, an enzyme found in muscles.
  • Electromyogram (EMG): Your child's electrical activity in the muscles can be measured with an EMG.
  • Muscle biopsy: This procedure examines alterations in the cells that make up your child's muscles.
  • Genetic testing: This method can detect alterations in the genes responsible for myopathy.

How is congenital myopathy treated?

Central core disease and multicore disease can be treated with albuterol. Albuterol is experimental, but it has been known to reduce the degree of weakness your child experiences. However, it does not cure the condition.

Managing your child's symptoms is the first step in treating any kind of congenital myopathy. These therapies ought to consist of:

  • Orthopaedic care, if required.
  • Physical treatment.
  • Occupational therapy.
  • Speech therapy.
  • More experimental treatments, such as gene therapies, are currently under development.

How can I decrease the chance that my child will have congenital myopathy?

Since congenital myopathy is a result of a genetic alteration, the condition itself cannot be prevented. If you are concerned about having a baby with a genetic condition, you should discuss your options for genetic counseling and possibly genetic testing with your medical professional.

How long will my child live if they have congenital myopathy?

Depending on your child's health and its severity, a variety of prognostic information is accessible. Long-term skeletal problems may also occur from congenital myopathy in the form of:

  • Reduced mobility at the joints
  • HIP problems.

Additionally, life expectancy varies. Your infant may suffer from respiratory failure or complications like pneumonia if they have severe breathing difficulties. On the other hand, your child might live a complete life if their disease is moderate. Discuss your child's particular condition with their healthcare professional.
