В гене описаны как точковые изменения последовательности, так и крупные структурные перестройки. Целью данного исследования было определение спектра мутаций гена F9 у российских больных гемофилией B. Проведено исследование 59 неродственных семей с направительным диагнозом «гемофилия B» методами секвенирования по Сэнгеру, массового параллельного секвенирования и количественного MLPA анализа. Мутации обнаружены в 86,4% случаев. Наибольшую долю среди выявленных патогенных вариантов составляют миссенс-мутации - 62,7%, на долю нонсенс-мутаций приходится 19,6%, крупных делеций, включающих один или несколько экзонов - 3,9%, мутаций со сдвигом рамки считывания - 5,9%, мутаций сайта сплайсинга - 2%, мутаций промотора - 5,9%, что в целом соответствует литературным данным. Четырнадцать выявленных нуклеотидных вариантов ранее не были описаны. Большинство из них являются миссенс-мутациями. Таким образом, было проведено изучение спектра мутаций у российских больных гемофилией B. Определение типа мутации, ее локализации в гене и белке позволит предсказать характер течения заболевания и подобрать оптимальное лечение.</p></abstract><trans-abstract xml:lang="en"><p>Hemophilia B is an X-linked recessive disease associated with blood clotting disorder caused by mutations in the coagulation factor IX (F9) gene. Both point sequence changes and large structural rearrangements were described in the gene. The aim of this study was to determine the spectrum of mutations in the F9 gene in Russian patients with hemophilia B. A study of 59 unrelated families with a referral diagnosis of “hemophilia B” was conducted using Sanger sequencing, mass parallel sequencing, and quantitative MLPA analysis. Mutations were detected in 86.4% of cases. The prevalent among the identified pathogenic variants were missense mutations - 62.7%; nonsense mutations account for 19.6%, large deletions involving one or more exons - 3.9%, mutations with a reading frame shift - 5.9%, splice site mutations - 2%, mutations in the promoter- 5.9%, which generally corresponds to the literature data. Fourteen identified nucleotide variants have not been previously described. Most of them were missense mutations. Thus, we studied the spectrum of mutations in Russian patients with hemophilia B. Determining the type of mutation and its localization in the gene and protein will allow to predict the course of the disease and to choose the optimal treatment.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гемофилия В</kwd><kwd>ген</kwd><kwd>F9</kwd><kwd>мутация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hemophilia B</kwd><kwd>gene</kwd><kwd>F9</kwd><kwd>mutation</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">Berntorp E., Shapiro A.D.
