При этом по данным литературы одним из заболеваний, маскирующимся под него, можно считать синдром ювенильного полипоза, относящийся к гамартомным полипозным синдромам, однако по эндоскопической картине зачастую напоминающий одну из форм аденоматозного полипоза. В статье представлено клиническое наблюдение за семьей, у членов которой на протяжении нескольких лет подозревали наличие семейного аденоматоза толстой кишки, и лишь проведение полноэкзомного секвенирования помогло установить диагноз синдрома ювенильного полипоза.</p></sec><sec><title>   Результаты</title><p>   Результаты: на основании особенностей семейного анамнеза, а также несколько необычной для семейного аденоматоза толстой кишки клинической картины заболевания у пациентки было проведено полноэкзомное секвенирование, в результате которого был выявлен ранее не описанный в литературе патогенный вариант в гене SMAD4 - c.705dupA (p.Gly236ArgfsTer28). Наличие аналогичной мутации удалось также подтвердить у 3 ближайших родственников пациентки.</p></sec><sec><title>   Выводы</title><p>   Выводы: принимая во внимание широкую фенотипическую вариабельность проявлений ювенильного полипоза, у больных с клинической картиной аденоматозного полипозного синдрома и отсутствием мутации в генах АРС и MutYH особую важность приобретает проведение генетического анализа на наличие мутаций в генах SMAD4 и BMPR1A.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>   Aim</title><p>   Aim: based on literature data and our own experience, to demonstrate the need for a meticulous family history harvesting in patients with suspected hereditary polyposis syndrome, as well as the importance of conducting a complex molecular genetic study.</p></sec><sec><title>   Materials and methods</title><p>   Materials and methods: the most known among hereditary polyposis syndromes is familial adenomatous polyposis (FAP).At the same time, according to the literature, one of the hamartomatous polyposis syndromes- juvenile polyposis - may mimic endoscopic picture of adenomatous polyposis. The article presents a clinical observation of a family whose members have been suspected of having FAP for several years, and only whole-exome sequencing helped to establish the diagnosis of juvenile polyposis syndrome.</p></sec><sec><title>   Results</title><p>   Results: based on the family history, as well as the clinical picture of the disease, which was somewhat unusual for FAP, the patient underwent whole-exome sequencing, which revealed a previously undescribed pathogenic variant in the SMAD4 gene - c.705dupA (p.Gly236ArgfsTer28). The presence of a similar mutation was also confirmed in 3 close relatives of the patient.</p></sec><sec><title>   Conclusion</title><p>   Conclusion: taking into account the wide phenotypic variability of manifestations of juvenile polyposis, molecular genetic study of the SMAD4 and BMPR1A genes is of particular importancein patients with a clinic of adenomatous polyposis syndrome and the absence of mutations in the APC and MutYH genes.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ювенильный полипоз</kwd><kwd>аденоматозный полипозный синдром</kwd><kwd>семейный аденоматоз толстой кишки</kwd><kwd>гамартомный полипозный синдром</kwd><kwd>ген SMAD4</kwd><kwd>полноэкзомное секвенирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>juvenile polyposis</kwd><kwd>adenomatous polyposis syndrome</kwd><kwd>familial adenomatous polyposis</kwd><kwd>hamartomatous polyposis syndrome</kwd><kwd>SMAD4</kwd><kwd>whole-exome sequencing</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">Цуканов А.
