Митохондрии играют важную роль в клеточном метаболизме, поскольку они отвечают за производство большинства клеточной энергии в виде аденозинтрифосфата. Мутации в митохондриальных генах отвечающих за функционирование митохондрий, могут привести к различным формам митохондриальных заболеваний. Эти заболевания могут проявляться следюущими клиническими симптомами: мышечная слабость, нарушения движения, неврологические симптомы, нарушение моторики и всасывания из желудочно-кишечного тракта. Диагностика митохондриальных заболеваний может представлять сложность из-за генетической и клинической гетерогенности. Лечение в настоящее время остается актуальной проблемой, так как исследования в этой области активно ведутся и появляются новые методы, направленные на терапию и лечение этих редких заболеваний.</p></abstract><trans-abstract xml:lang="en"><p>The article discusses the features of lesions of the digestive system in children with mitochondrial diseases. Mitochondria play an important role in cellular metabolism as they are responsible for producing the majority of cellular energy in the form of adenosine triphosphate. Mutations in mitochondrial genes responsible for the functioning of mitochondria can lead to various forms of mitochondrial diseases. These diseases may present with the following clinical symptoms: muscle weakness, movement disorders, neurological symptoms, impaired motility and absorption from the gastrointestinal tract. Diagnosis of mitochondrial diseases can be challenging due to genetic and clinical heterogeneity. Treatment currently remains a pressing problem, as research in this area is being actively conducted and new methods are emerging aimed at the therapy and treatment of these rare diseases.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>митохондрии</kwd><kwd>митохондриальные заболевания</kwd><kwd>пищеварительная система</kwd><kwd>митофагия</kwd><kwd>митохондриальная ДНК</kwd><kwd>ядерная ДНК</kwd><kwd>мутации</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mitochondria</kwd><kwd>mitochondrial diseases</kwd><kwd>digestive system</kwd><kwd>mitophagy</kwd><kwd>mitochondrial DNA</kwd><kwd>nuclear DNA</kwd><kwd>mutations</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">Mitochondrial and Microbiota Relationship.
