Важным фактором, влияющим на фенотипические проявления МВ и эффективность таргетной терапии, является наличие комплексных аллелей — &gt; 2 последовательных мутаций на 1-м аллеле, или в цис-положении. Влияние комплексных аллелей на проявления МВ в мире изучено недостаточно из-за небольшого количества проведенных исследований.</p><p>Целью исследования явилось изучение влияния комплексного аллеля [S466X; R1070Q] на фенотипические проявления МВ и эффективность таргетной терапии на модели кишечных органоидов у пациента с генотипом [S466X; R1070Q]/CFTRdele2,3.</p><sec><title>Материалы и методы</title><p>Материалы и методы.

An important factor affecting the phenotypic manifestations of CF and the effectiveness of targeted therapy is the presence of complex alleles with &gt; 2 consecutive mutations per 1 allele, or in the cis position. The influence of complex alleles on the manifestations of CF has not been sufficiently studied globally due to the small number of studies.</p><p>The aim of the study was to investigate the influence of the complex allele [S466X; R1070Q] on the phenotypic manifestations of CF and the effectiveness of targeted therapy in a model of intestinal organoids from a patient with [S466X; R1070Q]/CFTRdele2,3 genotype.</p><sec><title>Methods</title><p>Methods.
