Patient's question:
My cousin has always been afraid to get married and start a career because my aunt suffers from severe myasthenia gravis. My cousin is worried that this disease might be inherited to the next generation, so she has rejected all the boys who have a good impression on her. I want to ask the doctor, how does severe myasthenia gravis have a genetic component?Doctor's answer:
Genetic factors across generations are one of the causes of myasthenia gravis, but the proportion is very low. Some familial myasthenia gravis patients have a strong correlation with genetic inheritance across generations. Myasthenia gravis is a disease that can be inherited across generations, but it does not have an infectious nature. Because this disease is genetic, from the perspective of eugenics, patients with genetic diseases should avoid pregnancy. If they must have children, prenatal examinations should be conducted promptly.
