1. Myasthenia gravis
Myasthenia gravis is a disorder of neuromuscular transmission in which the acetycholine receptors are blocked by autoantibodies. As a result, there is weakness of muscles, initially the extra-ocular muscles leading to diplopia, later the respiratory muscles and muscles for movement. Inheritance is usually sporadic. In 1 to 4% of cases there is apparently a familial tendency to get the disease, but there is not an easily discernable pattern of inheritance.

2. Plasmapheresis
This is a medical method in which some blood is removed from a person. The blood cells, after being separated from the plasma (usually via centrifugation ), are returned to the person. It has been speculated that this method removes certain proteins that are deleterious to the person, such as autoantibodies. Some limited success has been achieved in the treatment of conditions including: myasthenia gravis (MG), Eaton-Lambert syndrome (ELS), chronic inflammatory demyelinating polyneuropathy (CIDP), Guillain-Barre syndrome (GBS), paraproteinemia, amyotrophic lateral sclerosis (ALS), and multiple sclerosis (MS).
