Показано, что геномы больных муковисцидозом содержат увеличенное количество копий рДНК (289 - 932; среднее: 563 ± 101; N = 203) по сравнению со здоровыми людьми (171-711; среднее 420 ±107 копий; N = 751) того же возраста (p &lt;10-33). В выборке больных и в контрольной выборке наблюдали сужение интервала варьирования числа копий рДНК в старших возрастных группах. В группе больных возраста 30-66 лет интервал варьирования числа копий рДНК в геноме сужен до 430-680 копий (среднее: 544±72 копии; N=27). Потенциально число копий рДНК в геноме больных муковисцидозом можно рассматривать как дополнительный прогностический маркер, отражающий продолжительность жизни больного.</p></abstract><trans-abstract xml:lang="en"><p>The number of copies of tandem ribosomal repeat (rDNA) in the DNA of blood leukocytes of patients with cystic fibrosis of various ages (from 0 to 66 years) was determined for the first time. It was shown that the genomes of patients with cystic fibrosis contain an increased number of rDNA copies (289 - 932; mean: 563 ± 101; N = 203) compared with healthy people (171 - 711; mean 420 ± 107 copies; N = 751) of the same age (p &lt;10-33). In the sample of patients and in the control sample, a narrowing of the range of variation in the rDNA copy number was observed in older age groups. In the group of patients aged 30-66 years, the interval of variation in the number of rDNA copies in the genome was narrowed to 430-680 copies (mean: 544 ± 72 copies; N = 27). Potentially, the number of rDNA copies in the genome of patients with cystic fibrosis can be considered an additional prognostic marker reflecting the patient’s life expectancy.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рибосомные гены</kwd><kwd>рДНК</kwd><kwd>муковисцидоз</kwd><kwd>число копий рДНК</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ribosomal genes</kwd><kwd>rDNA</kwd><kwd>cystic fibrosis</kwd><kwd>rDNA copy number</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">Laferté A., Favry E., Sentenac A., et al.
