Благодаря развитию молекулярно-генетических методов диагностики идентифицировано более 90 наследственных форм ЭЭ, большее число которых открыто за последнюю декаду. ЭЭ могут быть связаны с нарушением молекулярной функции транспортеров нейронов (потенциал-зависимые и лиганд-зависимые переносчики), нарушениями обмена веществ, хромосомными болезнями. Среди моногенных ЭЭ выделяют группу заболеваний, при которых повреждение головного мозга и развитие эпилепсии обусловлено наследственными нарушениями митохондриальных функций. Учитывая большое разнообразие форм митохондриальных дисфункций, отсутствие специфических проявлений, различный возраст манифестации, диагностика этой группы заболеваний не является рутинным процессом и требует генетических методов исследования, в том числе расширенных методов ДНК-диагностики (полно-экзомные/-геномные, панели генов). С созданием новых препаратов, корригирующих митохондриальные нарушения, своевременная диагностика митохондриальных дисфункций, определение генетического нарушения способствуют своевременному началу патогенетического лечения, выбору антиэпилептического препарата, что может снизить риск летальности и степень инвалидизации пациента. Мы описываем случай ранней неонатальной эпилепсии в структуре наследственной недостаточности коэнзима Q10. Однако, к сожалению, поздно начатая специальная энерготропная терапия и тяжелое течение болезни привели к раннему летальному исходу. Наследственные дефекты коэнзима Q являются редкой генетической патологией. В этой связи для врачей, ведущих больного, обнаружение именного этого дефекта было скорее всего «неожидаемой» находкой. Учитывая сложность выполнения и длительность проводимого полноэкзомного исследования, тяжесть фенотипа и отсрочку энерготропной терапии, течение заболевания у ребенка оказалось крайне неблагоприятным. Представление клинического случая, по нашему мнению, будет иметь важное значение для практикующих врачей, редко сталкивающимися с данным видом патологи.</p></abstract><trans-abstract xml:lang="en"><p>Epileptic encephalopathy (EE) is a group of genetic monogenic diseases with leading feature of intractable epilepsy with onset at an early age and the development of neurocognitive deficit. Thanks to the development of molecular genetic diagnostic methods, more than 90 hereditary forms of EE have been identified, more of which have been discovered over the past decade. EE can be associated with impaired molecular function of neuron transporters (voltage-dependent and ligand-dependent transporters), metabolic disorders, and chromosomal diseases. Among monogenic EE, a group of diseases is distinguished, in which brain damage and the development of epilepsy are caused by hereditary disorders of mitochondrial functions. Given the wide variety of forms of mitochondrial dysfunctions, the absence of specific manifestations, different age of manifestation, the diagnosis of this group of diseases is not a routine process and requires DNA test (whole-exome/genome sequencing, gene panels). With the creation of new drugs that correct mitochondrial disorders, in-time diagnosis of mitochondrial dysfunctions, identification of a genetic disorder contributes to the in-time manage of pathogenetic treatment, the choice of an antiepileptic drug, which can reduce the risk of mortality and the degree of patient disability. We describe the case of early neonatal epilepsy in the structure of hereditary deficiency of coenzyme Q10. However, unfortunately, the late started specifical energotropic therapy and the severe course of the disease led to an early death. Hereditary defects in coenzyme Q are rare genetic disorders. In this regard, for the specialists leading the patient, the discovery of this particular defect was most likely an “unexpected” finding. Considering the complexity and duration of the whole exome study, the severity of the phenotype and the delay in energotropic therapy, the course of the disease in the child turned out to be extremely unfavorable. The presentation of the clinical case, in our opinion, will be important for practitioners who rarely encounter this type of pathology.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>медицина</kwd><kwd>неонатология</kwd><kwd>реаниматология</kwd><kwd>неврология</kwd><kwd>генетика</kwd><kwd>молекулярная биология</kwd></kwd-group><kwd-group xml:lang="en"><kwd>medicine</kwd><kwd>neonatology</kwd><kwd>neurology</kwd><kwd>genetics</kwd><kwd>molecular biology</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Stenton S.
