Наличие комплексных аллелей может модифицировать клинический фенотип, однако данные о влиянии аллеля [L467F;F508del] ограничены.</p><p>Целью исследования являлось проведение сравнительного анализа клинических проявлений заболевания в двух когортах российских пациентов с МВ в возрасте до 18 лет, различающихся по генотипу CFTR: [L467F;F508del]/I класс и F508del/I класс.</p><sec><title>Материалы и методы</title><p>Материалы и методы. Проведено ретроспективное когортное исследование на основе данных Национального регистра пациентов с МВ за 2023 г. В исследование включены пациенты с МВ (n = 100) моложе 18 лет, которые были распределены на 2 группы: 1-я (n = 22) – с генотипом [L467F;F508del]/I класс; 2-я (n = 78) – с генотипом F508del/I класс. Сравнивались возраст на момент проведения исследования, пол, возраст установления диагноза, доля диагнозов, установленных по результатам неонатального скрининга, наличие мекониевого илеуса в анамнезе, микробный пейзаж дыхательных путей, функция внешнего дыхания (ФВД), нутритивный статус, частота осложнений и проводимая терапия.</p></sec><sec><title>Результаты</title><p>Результаты. Группы были сопоставимы по возрасту, полу, возрасту установления диагноза и результатам неонатального скрининга. Статистически значимых различий показателей ФВД и нутритивного статуса не выявлено. Частота цирроза печени была выше в группе [L467F;F508del]/I класс (22,7 % vs 5,1 %; p = 0,038). В этой же группе более частым оказался высев Achromobacter spp. (13,6 % vs 2,6 %; p = 0,044). Различий других показателей осложнений не отмечено.</p></sec><sec><title>Заключение</title><p>Заключение. Наличие комплексного аллеля [L467F;F508del] не приводит к статистически значимым изменениям функции легких и нутритивного статуса по сравнению с F508del/I класс, однако может влиять на микробиологический статус и частоту поражения печени. Благодаря этим результатам подчеркивается значимость молекулярно-генетического уточнения комплексных аллелей CFTR при стратификации риска осложнений и планировании персонализированной терапии у детей с МВ.</p></sec></abstract><trans-abstract xml:lang="en"><p>Cystic fibrosis (CF) is an autosomal recessive disease caused by CFTR mutations. The presence of complex alleles can modify the clinical phenotype, but data on the impact of [L467F;F508del] are limited.</p><p>The aim of the study was to compare the clinical manifestations in two cohorts of Russian patients with cystic fibrosis (CF) under 18 years of age with [L467F;F508del]/class I or F508del/class I genotype of CFTR.</p><sec><title>Methods</title><p>Methods. A single-center retrospective cohort study was conducted using data from the Russian National CF Patient Registry for 2023. The study included 100 patients under 18 years: 22 with the [L467F;F508del]/class I genotype (group 1) and 78 with F508del/class I (group 2). The study compared their age at enrollment, sex, age at diagnosis, proportion of diagnoses established through neonatal screening, history of meconium ileus, airway microbiological profile, lung function, nutritional status, frequency of complications, and ongoing therapy.</p></sec><sec><title>Results</title><p>Results. The groups were comparable in terms of age, sex, age at diagnosis, and neonatal screening results. No statistically significant differences were observed in lung function or nutritional status. The frequency of liver cirrhosis was higher in the [L467F;F508del]/class I group (22.7% vs 5.1%; p = 0.038). This group also had a higher prevalence of Achromobacter spp. colonization (13.6% vs 2.6%; p = 0.044). No significant differences were found for other complications.</p></sec><sec><title>Conclusion</title><p>Conclusion. The presence of the [L467F;F508del] complex allele does not lead to statistically significant changes in lung function or nutritional status compared to F508del/class I, but may influence the microbiological profile and the frequency of liver involvement. These findings highlight the importance of molecular-genetic characterization of complex CFTR alleles for risk stratification and the planning of personalized therapy in children with cystic fibrosis.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>муковисцидоз</kwd><kwd>CFTR</kwd><kwd>комплексный аллель</kwd><kwd>F508del</kwd><kwd>L467F</kwd><kwd>генотип-фенотип</kwd><kwd>цирроз</kwd><kwd>микробиологический статус</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cystic fibrosis</kwd><kwd>CFTR</kwd><kwd>complex allele</kwd><kwd>F508del</kwd><kwd>L467F</kwd><kwd>genotype-phenotype correlation</kwd><kwd>cirrhosis</kwd><kwd>airway microbiology</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках исполнения гранта Российского научного фонда № 22-15-00473-П «Исследование влияния комплексных аллелей гена CFTR на функциональную активность хлорного канала для персонализированного подбора таргетной терапии при муковисцидозе (2025–2026)».</funding-statement><funding-statement xml:lang="en">This study was supported by the Russian Science Foundation, grant No. 22-15-00473-П “Investigation of the impact of CFTR complex alleles on chloride channel functional activity for personalized selection of targeted therapy in cystic fibrosis.”</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">Castellani C., Assael B.M.
