Целью работы стало исследование частоты шести SNP в генах системы витамина D – VDR и GC – у пациентов с РС (n=145) и в группе популяционного контроля (ПК, n=96). ДНК, выделенную из образцов крови, генотипировали методом ПЦР в режиме реального времени. Обсуждаются частота и спектр исследованного комплекса SNP. Исследование выявило 22 варианта сочетаний SNP в группе популяционного контроля и 15 вариантов в группе пациентов с РС. Наиболее распространенным у больных РС оказался вариант GCCCGC. Выявлено два варианта, которые встречались в сравниваемых группах с разной частотой – GCCCGA и GCCCAC. Полученные результаты свидетельствуют в пользу данных о взаимосвязи генов системы витамина D с развитием РС.</p></abstract><trans-abstract xml:lang="en"><p>Studies have shown that the level of vitamin D and polymorphisms in the genes of the vitamin D system are factors associated with susceptibility to the development of multiple sclerosis. The purpose of this work was to investigate the frequency of six SNPs in the genes of the vitamin D system – VDR and GC – in patients with multiple sclerosis (MS, n=145) and in a population control group (CG, n=96). DNA, extracted from blood samples, was genotyped using real-time PCR. The frequency and spectrum of the investigated SNP combinations are discussed. The study identified 22 variant combinations of SNPs in the population control group and 15 variants in the MS patient group. The most common variant among MS patients was GCCCGC. Two variants were identified that occurred with varying frequencies – GCCCGA and GCCCAC. The results obtained support the data on the correlation of vitamin D system genes with the development of MS.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рассеянный склероз</kwd><kwd>гены</kwd><kwd>VDR</kwd><kwd>GC</kwd><kwd>SNP-полиморфизм</kwd></kwd-group><kwd-group xml:lang="en"><kwd>multiple sclerosis</kwd><kwd>genes</kwd><kwd>VDR</kwd><kwd>GC</kwd><kwd>SNP-polymorphism</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при частичном финансировании гранта Российского научного фонда № 22-25-20209, https://rscf.ru/project/22-25-20209 и Министерства науки и высшего образования Кузбасса.</funding-statement><funding-statement xml:lang="en">This work was partially supported by grant No. 22-25-20209 of the Russian Science Foundation and the Ministry of Science and Higher Education of Kuzbass.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Wingerchuk D.M., Carter J.L.
