Hi The Chef
Welcome to NeuroTalk

.
Myasthenia Gravis is an autoimmune disease. That means that your immune system recognises normal body proteins as being foreign in a way which is similar to if you have a bacterial or viral infection.
The specific normal body proteins which are involved in Myasthenia Gravis are naturally found at neuromuscular junctions. Two of these are the acetylcholine receptor and the MuSK protein.
There is some general information about Myasthenia Gravis here
Myasthenia Gravis Fact Sheet | National Institute of Neurological Disorders and Stroke .
