Опосредованное им повышение уровня интерферонов и экспрессии индуцируемых ими генов играет ключевую роль в развитии как системной красной волчанки (СКВ), так и ее проявления – люпус нефрита (ЛН). В работе определены частоты генотипов и аллелей в полиморфных локусах генов STAT4 (rs7574865, rs3821236), PTPN2 (rs2542151, rs7234029) и PTPN22 (rs2476601) в группах детей (n = 37) и взрослых (n = 63) с СКВ и ЛН. В контрольную группу включены дети (n = 420) и взрослые (n = 345) без аутоиммунных заболеваний. Анализ объединенной группы пациентов детского и взрослого возраста позволил установить, что полиморфный локус rs7574865 гена STAT4 является маркером риска развития СКВ (Т: OR 1,99 [1,42–2,79], р = 0,0001; TT: OR 3,36 [1,64–6,87], р = 0,0018) и ЛН (Т: OR 1,91 [1,32–2,78], р = 0,0008; TT: OR 4,25 [2,02–8,95], р = 0,0004). Эти ассоциации сохранялись и при анализе детской и взрослой групп пациентов с СКВ и ЛН по отдельности. При этом полиморфный локус rs7574865 гена STAT4 является, по-видимому, общим генетическим фактором риска возникновения аутоиммунных заболеваний. Также выявлена ассоциация полиморфного локуса rs2542151 гена PTPN2 с риском развития СКВ (G: OR 1,66 [1,12–2,47], p = 0,014; GT: OR 1,74 [1,10–2,77], р = 0,021) и ЛН (G: OR 1,87 [1,21–2,88], р = 0,006; GT: OR 1,90 [1,13–3,18], р = 0,017) в объединенной группе пациентов. Полиморфные локусы rs7234029 гена PTPN2 и rs2476601 гена PTPN22 не были ассоциированы с СКВ или ЛН вне зависимости от возраста пациентов.</p></abstract><trans-abstract xml:lang="en"><p>Genes of interest – STAT4, PTPN2 and PTPN22 – are components of the JAK-STAT signaling pathway, one of the important regulators of the immune system. The JAK-STAT pathway plays a key role in the development of both systemic lupus erythematosus (SLE) and its manifestation, lupus nephritis (LN) by mediating interferon levels and promoting IFN-induced gene expression. We investigated the allele and genotypes frequencies at the polymorphic loci of the STAT4 (rs7574865, rs3821236), PTPN2 (rs2542151, rs7234029) and PTPN22 (rs2476601) genes in groups of children (n = 37) and adults (n = 63) with SLE and LN. The control group included children (n = 420) and adults (n = 345) without autoimmune diseases. The analysis of the combined group of pediatric and adult patients revealed that the rs7574865 polymorphic locus of the STAT4 gene is associated with the risk of developing SLE (Т: OR 1,99 [1,42–2,79], р = 0,0001; TT: OR 3,36 [1,64–6,87], р = 0,0018) and LN (Т: OR 1,91 [1,32–2,78], р = 0,0008; TT: OR 4,25 [2,02–8,95], р = 0,0004). These associations also persisted when analyzing the pediatric and adult groups of patients with SLE and LN separately. Moreover, the rs7574865 polymorphic locus of the STAT4 gene appears to be a common genetic risk factor for autoimmune diseases development. The association of the polymorphic locus rs2542151 of the PTPN2 gene with the SLE (G: OR 1,66 [1,12–2,47], p = 0,014; GT: OR 1,74 [1,10–2,77], р = 0,021) and LN (G: OR 1,87 [1,21–2,88], р = 0,006; GT: OR 1,90 [1,13–3,18], р = 0,017) susceptibility was also found in a combined group of patients. The polymorphic loci rs7234029 in the PTPN2 gene and rs2476601 in the PTPN22 gene were not associated with SLE or LN regardless of the age of the patients.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>системная красная волчанка</kwd><kwd>люпус нефрит</kwd><kwd>STAT4</kwd><kwd>PTPN2</kwd><kwd>PTPN22</kwd></kwd-group><kwd-group xml:lang="en"><kwd>systemic lupus erythematosus</kwd><kwd>lupus nephritis</kwd><kwd>STAT4</kwd><kwd>PTPN2</kwd><kwd>PTPN22</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">Козыро, И.
