The article presents a clinical case demonstrating the difficulty of differential diagnosis of POLG-associated disease and juvenile myoclonic epilepsy. The case demonstrates the importance of molecular genetic diagnosis in idiopathic generalized epilepsy with atypical features for timely administration of appropriate therapy and minimize the development of adverse side reactions.</p></abstract><trans-abstract xml:lang="ru"><p>Мутации гена POLG могут приводить к целому ряду клинических проявлений, в том числе к аутосомно-рецессивным или аутосомно-доминантным митохондриальным заболеваниям. В статье представлен клинический случай, демонстрирующий сложность дифференциальной диагностики POLG-ассоциированного заболевания и юношеской миоклонической эпилепсии.
