What is MG?

Myasthenia gravis (MG) is a chronic autoimmune disease

THE IMPACT OF MG

MG can make daily tasks
more difficult

 

Myasthenia gravis (MG) results from a problem in signaling between nerves and muscles.

This problem happens in the neuromuscular junction, the place where nerves meet the muscles they control.

Generalized myasthenia gravis (gMG) is a more serious form of MG that can weaken muscles throughout the entire body. gMG can affect your nerves and muscles, causing muscle weakness and fatigue that can feel overwhelming. These symptoms can be debilitating and often result in symptoms that can make activities of daily living like climbing stairs, chewing, or brushing your teeth very challenging.

What causes gMG and its symptoms?

 

gMG is caused by antibodies in your immune system that get in the way of signals between nerves and muscles at the neuromuscular junction.

Harmful antibodies, such as anti-AChR (acetylcholine receptor) and anti-MuSK (muscle-specific tyrosine kinase) antibodies, cause the symptoms of gMG.

Most people with gMG have either anti-AChR or anti‑MuSK antibodies, but usually not both.

Signals are sent from nerves and received by muscles as part of normal muscle function and movement.
Harmful antibodies block these signals, resulting in damage to muscle cells and the symptoms of gMG.
