Статья посвящена клиническому полиморфизму митохондриальных болезней на примере мутации A3243G в митохондриальной ДНК. Рассматриваются клинические критерии и алгоритм диагностики митохондриальных заболеваний.Материал и методы. Представлены три пациента с мутацией A3243G в митохондриальной ДНК. Всем пациентам проводилось клиническое неврологическое обследование, инструментальное обследование (ЭКГ, ЭхоКГ, МРТ и КТ головного мозга, ЭЭГ, игольчатая и стимуляционная электромиография, аудиометрия), биохимическое исследование уровня молочной и пировиноградной кислот в крови до и после нагрузки, биопсия мышцы.Результаты. У всех пациентов были выявлены миопатия, непереносимость физических нагрузок, нейросенсорная тугоухость, низкорослость; другие симптомы варьировали. По результатам биопсии мышцы феномен «рваных красных волокон» обнаружен у двух пациентов. Диагноз был подтвержден при молекулярно-генетическом обследовании.Заключение. Митохондриальные заболевания при одной и той же мутации характеризуются значительной вариабельностью клинической картины. Выявление характерных для группы митохондриальных болезней клинических признаков должно насторожить врача в отношении данной патологии для проведения необходимого обследования.</p></abstract><trans-abstract xml:lang="en"><p>The article is devoted to the clinical polymorphism of mitochondrial diseases by the example of A3243G mutation in mitochondrial DNA. The article also discusses clinical criteria and an algorithm for the diagnosis of mitochondrial diseases.Material and methods. Тhree families with A3243G mutation in mitochondrial DNA are presented. All patients underwent clinical neurological examination, instrumental examination (ECG, Echo-CG, MRI and CT of the brain, EEG, needle and stimulation electromyography, audiometry), biochemical study of the level of lactic and pyruvic acids in the blood before and after exercise, muscle biopsy.Results. Аll patients had myopathy, exercise intolerance, sensorineural hearing loss, short stature; other symptoms varied. According to the results of muscle biopsy, the phenomenon of «ragged red fibers» was found in two patients. The diagnosis was confirmed by molecular genetic examination. Conclusion. Мitochondrial diseases with the same mutation are characterized by significant variability of clinical symptoms. The identification of clinician traits characteristic of a group of mitochondrial diseases should alert the doctors to this pathology.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>митохондриальные заболевания</kwd><kwd>мутация m.3243A&gt;G</kwd><kwd>«рваные красные волокна»</kwd><kwd>MELAS</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mitochondrial diseases</kwd><kwd>A3243G mutation</kwd><kwd>“ragged red fibers”</kwd><kwd>MELAS</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">Craven L., Alston C.L., Taylor R.W., Turnbull D.M.
