Guillain-Barré syndrome is not a genetic disorder, it is an immune-mediated peripheral neuropathy, and immune-mediated peripheral neuropathy is primarily inflammation of the peripheral nerves. Normally, when a pathogen enters the body, the immune system clears it. However, under special circumstances, after the pathogen enters the system, due to the similarity of certain structures of the pathogen and the structures within the normal tissues of the human body, when the immune system attacks the pathogen and clears the pathogen, the ability to recognize the enemy and the self becomes abnormal, and in addition to attacking and clearing the pathogen, it also attacks and clears the body’s normal own tissues. Guillain-Barré syndrome, for example, attacks its own peripheral nerves, resulting in symptoms such as numbness, weakness, and flaccid paralysis of the limbs. Generally Guillain-Barré is mainly caused by autoimmune abnormalities and environmental factors, including infections, vaccinations, and other etiologic factors, and has little to do with genetics.
