Is Myasthenia Gravis Hereditary?

Q:
Is myasthenia gravis hereditary?

A:

Currently reseachers believe genetic factors may be associated with myasthenia gravis.

In myasthenia gravis, antibodies are produced from a person’s immune system that block or destroy many of the muscles’ receptor sites. That’s the cause of myasthenia gravis. Some people may have myasthenia gravis that isn’t caused by antibodies blocking the muscle-specific receptor, this type of myasthenia gravis is called antibody-negative myasthenia gravis.

Rarely, some children are born with a hereditary form of myasthenia, called congenital myasthenic syndrome.

Congenital myasthenic syndromes are rare genetic conditions resulting from a defect at the junction where your nerve stimulates muscle activity. That defect causes muscle weakness.

Congenital myasthenic syndromes may affect your nerve cells, your muscle cells, or the space between your nerve and muscle cells.
