Early identification of patients with psoriasis with an increased risk of developing psoriatic arthritis for the purpose of its timely diagnosis and early initiation of therapy can prevent the development of severe disease outcomes. It is believed that the genes of the <italic>HLA</italic> system make the greatest individual genetic contribution to the formation of a predisposition to hereditary diseases with polygenic inheritance. The literature review considers the polymorphisms of the genes of the <italic>HLA</italic> system, associated with the development of psoriatic arthritis, in patients with psoriasis. The <italic>HLA</italic> alleles that contribute to the development of psoriatic arthritis and its individual forms have been identified. <italic>HLA </italic>alleles have been identified, which have a protective effect against the development of psoriatic arthritis.</p></abstract><trans-abstract xml:lang="ru"><p>Псориаз артропатический (псориатический артрит) часто приводит к развитию тяжелых исходов — анкилозов, деформаций пораженных суставов с выраженным нарушением их функций и инвалидности. Раннее выявление больных псориазом с повышенным риском развития псориатического артрита с целью его своевременной диагностики и раннего начала терапии может предотвратить развитие тяжелых исходов болезни. Считается, что наибольший индивидуальный генетический вклад в формирование предрасположенности к наследственным заболеваниям с полигенным наследованием вносят гены системы <italic>HLA</italic>. В обзоре литературы рассмотрены полиморфизмы генов системы <italic>HLA</italic>, ассоциированные с развитием псориатического артрита у больных псориазом. Определены аллели <italic>HLA</italic>, способствующие развитию псориатического артрита и его отдельных форм. Выделены аллели <italic>HLA</italic>, которые обладают протективным эффектом в отношении развития псориатического артрита.</p></trans-abstract><kwd-group xml:lang="en"><kwd>psoriatic arthritis</kwd><kwd>HLA genes</kwd><kwd>HLA-B*27</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>псориатический артрит</kwd><kwd>гены системы HLA</kwd><kwd>HLA-B*27</kwd></kwd-group><funding-group><funding-statement xml:lang="en">the work was done through financing at the place of work of the authors</funding-statement><funding-statement xml:lang="ru">работа выполнена за счет финансирования по месту работы авторов</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Blauvelt A, Chiricozzi A.
