There are three forms of the disease: infant, juvenile and adult. We present the clinical case of a patient born in 2004 (16 years old) with a debut of the disease at the age of 4 years with complex ticks. further neurological symptoms progressed and appeared atactic gait, intention tremor by performing coordination tests, muscle hypotension, decreased tendon reflexes, nasal voices, and behavior changes.Magnetic resonance imaging revealed changes in the white matter of both frontal lobes. An analysis was made of 59 genes of the panel “Leukodystrophy/leukoencephalopathy” by the method of mass parallel sequencing on the Ion S5. A mutation of the <italic>GFAP </italic>gene (Nm_002055), 4 exon c.758C&gt;A, p.ALA253Asp in a heterozygous state, not described in Human Gene mutation Database, was detected. The patient was confirmed to have a diagnosis of Alexander disease. According to tractography, a decrease in the number of fibers in the frontal lobes was found.The patient is currently receiving symptomatic treatment.</p></abstract><trans-abstract xml:lang="ru"><p>Болезнь Александера – одна из форм лейкоэнцефалопатии, которую вызывают мутации в гене <italic>GFAP</italic>. На сегодняшний день различают 3 формы заболевания: младенческую, юношескую и взрослую. Мы представляем клинический случай пациентки 2004 г.р. (16 лет) с дебютом заболевания в возрасте 4 лет со сложных тиков. Далее неврологическая симптоматика прогрессировала, появились атактическая походка, интенционный тремор при выполнении координационных проб, мышечная гипотония, снижение сухожильных рефлексов, гнусавость голоса, изменения поведения.При проведении магнитно-резонансной томографии были обнаружены изменения белого вещества обеих лобных долей. При проведении анализа 59 генов панели «Лейкодистрофии/лейкоэнцефалопатии» методом массового параллельного секвенирования на приборе Ion S5 выявлена мутация гена <italic>GFAP</italic><italic> </italic>(Nm_002055), 4-й экзон с.758C&gt;A, p.ALA253Asp в гетерозиготном состоянии, не описанная в Human Gene mutation Database.
