Цель исследования: Изучить связь между вариантом риска ZNF804A rs1344706 и шизофренией с учетом типа ее течения и шизаффективным расстройством (ШАР), а также некоторыми клиническими особенностями этих заболеваний, прогностически важными для оценки их тяжести. Материалы и методы: Выборка больных состояла из 1458 человек, из них 1284 с диагнозом шизофрения и 174 с диагнозом ШАР Контрольная группа психически здоровых испытуемых включала в себя 1051человека. Для оценки тяжести заболевания использовали возраст начала болезни и общий балл по широко используемой при изучении шизофрении шкале PANSS. Генотипирование полиморфизма ZNF804A rs1344706 проводили с помощью метода полиморфизма длин рестрикционных фрагментов. Результаты: Обнаружено повышение частоты генотипа риска АА в группе больных шизофренией по сравнению с контрольной группой (р=0,03. ОШ 1,31, ДИ 95% 1,03-1,7). Анализ связи полиморфизма ZNF804A rs1344706 с клиническими характеристиками выявил значимый эффект генотипа (р=0,007) на суммарный балл PANSS в общей группе больных. Наибольшая выраженность симптомов отмечена в группе носителей генотипа риска АА, а наименьшая &amp;ndash; у носителей генотипа СС. Влияния генотипа на возраст начала заболевания не обнаружено. Заключение: Полученные результаты подтверждают известные данные, о том, что полиморфизм ZNF804A rs1344706 ассоциирован с заболеванием и его тяжестью, а вариантом риска является генотип АА.</p></abstract><trans-abstract xml:lang="en"><p>Background: Replication of genome-wide association study (GWAS) loci for schizophrenia in different populations as well as the study of their specificity for disease are important issues in searching for genetic factors of schizophrenia. The aim of the study: To search for the association of ZNF804A rs1344706 polymorphism with schizophrenia and schizoaffective disorder (SAD), as well as with clinical characteristics of these diseases, which are of prognostic value. Materials and methods: The study included 1458 patients diagnosed with schizophrenia (n=1284) or SAD (n=174) and a control group of healthy people (n=1051). Age-at-disease onset and the total score on the Positive and Negative Syndrome Scale were used to assess the severity of disease. Genotyping was performed using the restriction fragment length polymorphism technique. Results: There is an increase in the frequency of the risk genotype AA in the total group of patients compared to the control group (p=0,03, OR 1,31, CI 95% 1,03-1,7). An analysis of association between ZNF804A rs1344706 and clinical characteristics reveals a significant effect of genotype (p=0,007) on the severity of the disease measured with the Positive and Negative Syndrome Scale. The highest scores are in the group of genotype AA carriers and the lowest in the group of CC genotype carriers. No association between genotype and age-at disease onset was identified. Conclusion: The results confirm the earlier findings that the risk genotype AA of ZNF804A rs1344706 polymorphism is associated with schizophrenia and its severity.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>шизофрения</kwd><kwd>шизоаффективное расстройство</kwd><kwd>ZNF804A</kwd><kwd>rs1344706</kwd><kwd>симптомы</kwd><kwd>PANSS</kwd></kwd-group><kwd-group xml:lang="en"><kwd>schizophrenia</kwd><kwd>schizoaffective disorder</kwd><kwd>ZNF804A gene</kwd><kwd>rs1344706</kwd><kwd>symptoms</kwd><kwd>PANSS</kwd></kwd-group></article-meta></front><back><ack><p>Исследование выполнено при финансовой поддержке РФФИ в рамках научного проекта № 19-07-01119.</p></ack><ref-list><title>Список литературы</title><ref id="B1"><mixed-citation>Replicated association between the European GWAS locus rs10503253 at CSMD1 and schizophrenia in Asian population / W.
