Examinations were made in 222 patients diagnosed with Parkinson's disease and 318 healthy individuals, who were an ethnic Russian population from the Siberian Region. Genotyping using one single-nucleotide polymorphism was performed in three glutamatergic system genes: the polymorphisms were rs2650427 in the GRIN2A gene, rs4354668 in the SLC1A2 gene, and rs1954787 in the GRIK4 gene. The results were statistically processed using the SPSS Statistics 23.0. </p></sec><sec><title>Results and discussion</title><p>Results and discussion. In the group of patients with tremor-dominant PD, the GRIK4 polymorphism rs1954787 showed a considerable increase in frequency of the T allele (66.7%) and a reduction in that of the C allele (33.3%) as compared to their distribution in the control group (42.1 and 57.9%, respectively; χ2 =7.70; p=0.006). The odds ratio (OR) was calculated for all of the genotypes and alleles of the investigated polymorphisms; the ratio showed that the C allele of the GRIK4 polymorphism rs1954787 had a protective effect (OR, 0.36; 95% CI, 0.17–0.76), whereas the T allele (OR, 2.75; 95% CI, 1.32–5.75) and the homozygous TT genotype (OR, 3.40; 95% CI, 1.21–9.53) were found to predispose to the development of tremor-dominant PD. </p></sec><sec><title>Conclusion</title><p>Conclusion. The found significant association of the GRIK4 polymorphism rs1954787 with the tremor-dominant PD may suggest that abnormalities in the glutamatergic system play a role in the pathophysiological processes of the disease.</p></sec></abstract><trans-abstract xml:lang="ru"><p>В настоящее время болезнь Паркинсона (БП) все чаще рассматривается как мультисистемное расстройство, связанное с мультинейротрансмиттерной дисфункцией, поэтому актуальным является поиск генетических факторов риска, определяющих различные клинические варианты течения данного заболевания. </p><p>Цель исследования – изучение ассоциаций БП с полиморфными вариантами генов глутаматергической системы: GRIN2A, кодирующего NMDA-рецептор; SLC1A2, кодирующего глиальный глутаматный транспортер; GRIK4, кодирующего ионотропный глутаматный каинатный рецептор. </p><sec><title>Пациенты и методы</title><p>Пациенты и методы. Обследовано 222 пациента с диагнозом БП и 318 здоровых лиц русской популяции Сибирского региона. Выполнено генотипирование по одному однонуклеотидному полиморфизму трех генов глутаматергической системы: (rs2650427) GRIN2A, (rs4354668) SLC1A2 и (rs1954787) GRIK4. Статистическая обработка результатов проводилась при помощи программы SPSS 23.0. </p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Для полиморфного варианта rs1954787 гена GRIK4 в группе пациентов с дрожательной формой БП наблюдались значимое повышение частоты аллеля Т (66,7%) и снижение частоты аллеля C (33,3%) в сравнении с распределением в группе контроля (42,1 и 57,9% соответственно при χ2 =7,70; p=0,006). Для всех генотипов и аллелей исследуемых полиморфизмов было рассчитано отношение шансов (ОШ), которое показало, что аллель С полиморфизма rs1954787 гена GRIK4 обладает протективным эффектом (OШ 0,36; 95% ДИ 0,17–0,76), тогда как аллель Т (ОШ 2,75; 95% ДИ 1,32–5,75) и гомозиготный генотип TT (ОШ 3,40; 95% ДИ 1,21–9,53) предрасполагают к развитию дрожательной формы болезни Паркинсона. </p></sec><sec><title>Заключение</title><p>Заключение. Выявленная достоверная ассоциация полиморфизма rs1954787 гена GRIK4 с дрожательной формой БП позволяет предположить роль патологии глутаматергической системы в патофизиологических процессах данного заболевания. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>болезнь Паркинсона</kwd><kwd>однонуклеотидные полиморфизмы</kwd><kwd>ген GRIN2A</kwd><kwd>ген SLC1A2</kwd><kwd>ген GRIK4</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Parkinson's disease</kwd><kwd>single-nucleotide polymorphisms</kwd><kwd>GRIN2A gene</kwd><kwd>SLC1A2 gene</kwd><kwd>GRIK4 gene</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">Farrer MJ.
