VI: Diseases of the nervous system
G70-G73: Diseases of myoneural junction and muscle
The group of conditions known as diseases of the myoneural junction and muscle involve problems with the communication between nerves and muscles, or the health of the muscles themselves. These could be genetic or acquired problems, and they involve various systems in the body. Typical symptoms might include muscle weakness, fatigue, or stiffness, and these symptoms can vary greatly in severity depending on the specific condition. Some of these conditions might progress rapidly, while others might evolve slowly over years. Often, these conditions result from the body's immune system attacking its own tissues, from mutations in the genes that regulate muscle function, or from toxins or infections. These diseases can significantly impact a person's ability to control their muscles and lead to disability.
