Однако в литературе описаны случаи синдрома кошачьего глаза с частичной или полной трисомией 22-й хромосомы. В статье представлены описания трех нетипичных клинических случаев синдрома, один из которых сопровождался эпилепсией, в связи с чем он описан более детально. Клиническая картина описанных случаев не включала в себя классическую триаду синдрома. Данное исследование представляет новую информацию о возможных вариантах фенотипа синдрома кошачьего глаза, включая коморбидность с эпилепсией, вносит вклад в формирование базы данных, позволяющей детально и многосторонне изучить заболевание.</p></abstract><trans-abstract xml:lang="en"><p>Cat eye syndrome is a rare genetic pathology characterized by the presence of an additional small supernumerary marker chromosome formed from copies of a region of chromosome 22, resulting in partial tetrasomy. However, Cat eye syndrome cases with partial or complete trisomy of chromosome 22 are also reported. This article presents descriptions of three atypical clinical cases of the syndrome, one of which is comorbid by epilepsy, and therefore its description is more detailed. The clinical picture of these three cases did not include the classic triad of the syndrome. Current study provides new information on possible variants of the Cat eye syndrome phenotype, including comorbidity with epilepsy, and contributes to the formation of a database that allows for a detailed and comprehensive study of the Cat eye syndrome.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>синдром кошачьего глаза</kwd><kwd>трисомия 22-й хромосомы</kwd><kwd>симптоматическая фокальная эпилепсия</kwd><kwd>электроэнцефалография</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cat eye syndrome</kwd><kwd>trisomy 22</kwd><kwd>symptomatic focal epilepsy</kwd><kwd>electroencephalography</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена за счет средств Программы стратегического академического лидерства Казанского (Приволжского) федерального университета» (Приоритет-2030).</funding-statement><funding-statement xml:lang="en">The work was supported by the Kazan Federal University Strategic Academic Leadership Program (Volga Region) (PRIORITY-2030).</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">Berends M.J., Tan-Sindhunata G., Leegte B., van Essen A.J.
