OBJECTIVE To identify the molecular basis and elucidate the pathogenesis of a fatal congenital myasthenic syndrome. METHODS We performed clinical electrophysiology studies, exome and Sanger sequencing, and analyzed functional consequences of the identified mutation. RESULTS Clinical electrophysiology studies of the patient revealed several-fold potentiation of the evoked muscle action potential by high frequency nerve stimulation pointing to a presynaptic defect. Exome sequencing identified… CONTINUE READING
