Congenital myasthenia gravis is incurable. As the name suggests, congenital myasthenia gravis is a genetic defect that causes muscle weakness and atrophy in the limbs. Clinically, it can manifest as droopy eyelids, weakness in diction, weakness in sucking, weakness in coughing, or even weakness in the muscles of the limbs, and patients can have symptoms such as restricted movement, inability to run, and inability to take care of themselves in daily life. Congenital muscle weakness can occur at all ages, for example, infants at birth can present with cough weakness, sucking weakness, coughing sputum weakness, and even breathing weakness; symptoms can also appear in early childhood, for example, slow movement of limbs, easy to fall, running not fast, and difficulty in going upstairs in preschool; elderly people can also present with such symptoms, which belong to late onset congenital muscle weakness, and its clinical manifestations are similar to those of infants and young children. The clinical symptoms are similar to those of infants and young children. Congenital myasthenia gravis is a genetic disorder, and since gene therapy is not yet mature, there is no cure for this disease.
