Заболевание из группы ядерно наследуемых митохондриальных энцефаломиопатий, обусловлено мутацией в гене DARS2, характеризуется недостаточностью митохондриальной аспартил-тРНК-синтетазы. В статье представлены история описания заболевания, его генетические основы, особенности клинической картины, критерии диагностики, а также описаны 2 клинических случая заболевания у девочек в возрасте 9 и 17 лет.</p></abstract><trans-abstract xml:lang="en"><p>Leukoencephalopathy with predominant lesion of the brain stem, spinal cord and high blood lactate in the MR spectroscopy is a hereditary disease characterized by slowly progressing cerebellar, pyramidal disorders, disorders involving the lesion of posterior columns of the spinal cord and highly specific changes according to the data of MRI and magnetic resonanse spectroscopy of the brain and spinal cord. This disease is one of nuclear inherited mitochondrial encephalomyopathies, caused by mutations in the DARS2 gene and characterized by mitochondrial aspartyl-tRNA-synthetase deficiency. This article presents the record of the disease description, its genetic basis, clinical features and diagnostic criteria. The article describes two clinical cases of the disease in 9-year and 17-year old girls.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>лейкоэнцефалопатия с преимущественным поражением ствола мозга</kwd><kwd>спинного мозга и повышенным лактатом при МР-спектроскопии</kwd><kwd>клиническая картина</kwd><kwd>диагностика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>leukoencephalopathy with predominant lesion of the brain stem</kwd><kwd>spinal cord and high blood lactate in the MR spectroscopy</kwd><kwd>clinical aspect</kwd><kwd>diagnosis</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">Lee-Jun C.
