Congenital myasthenia is an inherited disorder that affects the transmission of signals to the muscles. It results from a variety of genetic defects at the molecules associated with neuromuscular transmission. Congenital myasthenia is not the same as myasthenia gravis, which is an autoimmune disorder. More than a dozen congenital myasthenic syndromes have been classified. Symptoms are usually noticed in early childhood and include drooping eyelids, facial weakness, and limb weakness. Parents of children with congenital myasthenia frequently show no symptoms of the disorder
