Сходная симптоматика отмечена у старшего сибса, мать страдает сахарным диабетом 1-го типа. Проведено секвенирование полного митохондриального генома пробанда. Несмотря на то что достоверно патогенных вариантов не выявлено, был обнаружен ряд индивидуальных особенностей митохондриальной ДНК, которые могут иметь клиническую значимость. Особый интерес представляют два варианта: m.T8477C и m.C12562G, обладающие достаточно высоким патогенным потенциалом. Для установления их роли требуются дальнейшие исследования митохондриальной ДНК матери и сибса. </p></abstract><trans-abstract xml:lang="en"><p>The paper considers a clinical case of a child with suspected mitochondrial encephalomyopathy: cyclic vomiting, evident fatigue, muscle weakness, headache, and difficulties in learning school material. The similar symptoms are noted in an older sibling; the mother suffers from type 1 diabetes mellitus. The entire mitochondrial genome was sequenced in the proband. Despite the fact that significantly pathogenetic variants have not been identified, there are a number of individual mitochondrial DNA characteristics that may be of clinical significance. Of particular interest are two variants: m.T8477C and C12562G, which have a sufficiently high pathogenic potential. To establish their role requires further investigations of mitochondrial DNA in the mother and sibling. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>энцефаломиопатия</kwd><kwd>митохондрии</kwd><kwd>митохондриальная ДНК</kwd><kwd>секвенирование</kwd><kwd>m.T8477C</kwd><kwd>m.C12562G</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>encephalomyopathy</kwd><kwd>mitochondria</kwd><kwd>mitochondrial DNA</kwd><kwd>sequencing</kwd><kwd>m.T8477C</kwd><kwd>m.C12562G</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">Chinnery P., Hudson G.
