В ней подробно рассмотрены ключевые гены и их полиморфизмы, связанные с метаболизмом и транспортом МТХ, а также влияние на эффективность и переносимость терапии МТХ. Целью исследования является проведение обзора результатов генетических исследований, направленных на поиск маркеров, которые могут влиять на индивидуальные различия в фармакокинетике МТХ; дать характеристику наиболее хорошо изученным генам, участвующим в фармакогеномике МТХ и генам-кандидатам у пациентов с ЮИА, В статье проведен анализ результатов генетических исследований, опубликованных ведущими международными профессиональными сообществами специалистов в данной сфере. Проведен поиск информации в сети PubMed, eLIBRARY.

It focuses on key genes and polymorphisms associated with MTX metabolism and transport, as well as their impact on the efficacy and tolerability of MTX therapy. The aim of the study is to review the results of genetic studies aimed at finding markers that can influence individual differences in the pharmacokinetics of MTX; to characterize the most well-studied genes involved in the pharmacogenomics of MTX and candidate genes in patients with JIA. The article analyzes the results of genetic studies published by leading international professional communities of specialists in this field. Information was searched in the PubMed and eLibrary networks.RU, Google Scholar, ClinPGx, by keywords.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ювенильный</kwd><kwd>идиопатический артрит</kwd><kwd>генетическое исследование</kwd><kwd>генные полиморфизмы</kwd><kwd>гены-переносчики</kwd><kwd>гены-кандидаты</kwd><kwd>метотрексат</kwd></kwd-group><kwd-group xml:lang="en"><kwd>juvenile idiopathic arthritis</kwd><kwd>genetic study</kwd><kwd>gene polymorphisms</kwd><kwd>carrier genes</kwd><kwd>methotrexate candidate genes</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">Pastore, S., Stocco, G., Favretto, D., De Iudicibus, S., Taddio, A., d’Adamo, P., Malusà, N., Addobbati, R., Decorti, G., Lepore, L., Ventura, A.
