Одним из независимых факторов риска признается гипергомоцистеинемия, которая может быть вызвана генетическими нарушениями. Цель исследования: анализ распространенности полиморфизма гена метилентетрагидрофолатредуктазы C 677T, определение уровня гомоцистеина среди лиц с ишемическим инсультом в молодом возрасте и у лиц без инсульта. Материалы и методы. Проанализированы данные 141 пациента молодого возраста с ишемическим инсультом, включая 30 человек с атеротромботическим подтипом ишемического инсульта, 35 – с кардиоэмболическим, 36 – с лакунарным и 40 – с криптогенным подтипами инсульта. Контрольная группа включала 40 человек молодого возраста, не имевших инсульт в анамнезе. Результаты. Частота полиморфизма MTHFR C 677T (ОШ = 6,7; 95 % ДИ: 1,20–37,45; р = 0,027), аллеля Т (ОШ = 2,29; 95 % ДИ: 1,10–4,74; р = 0,028) и уровень гомоцистеина (р = 0,04) достоверно выше у молодых лиц с ишемическим инсультом.</p></abstract><trans-abstract xml:lang="en"><p>Number of young people with ischemic stroke increases at the present. One of independent risk factors of stroke is hyperhomocysteinemia, wich can be caused by genetic disorders. Objective: to analyze frequency of gene polymorphism of methylentetrahydrofolate reductase C 677T and level of homocysteine among patients with stroke and people without one. Materials and methods. Data of 141 young patients with ischemic stroke, including 30 people with atherothrombotic stroke, 35 with cardioembolic, 36 with lacunar and 40 ones with cryptogenic stroke were analyzed. The control group included 40 young patients without stroke. Results. The frequency of polymorphism MTHFR C 677T (OR = 6,7; 95 % CI: 1,20–37,45: р = 0,027), allel T (OR = 2,29; 95 % CI: 1,10–4,74; р = 0,028) and the level of homocysteine are higher among stroke patients.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ишемический инсульт в молодом возрасте</kwd><kwd>MTHFR C 677T</kwd><kwd>атеротромботический инсульт</kwd></kwd-group><kwd-group xml:lang="en"><kwd>young ischemic stroke</kwd><kwd>MTHFR C 677T</kwd><kwd>atherothrombotic stroke</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">Béjot Y., Bailly H., Durier J, et al.
