HNF1β является основным транскрипционным фактором, оказывающим влияние на развитие почек, половых путей, поджелудочной железы, печени, паращитовидных желез в период онтогенеза. Почечные проявления заболевания или HNF1β – ассоциированная нефропатия может быть представлена: врожденными аномалиями развития почек и мочевыводящих путей; поликистозом почек; тубулярными нарушениями. Внепочечными проявлениями HNF1β – ассоциированного заболевания могут быть: сахарный диабет взрослого типа у молодых тип 5 (MODY5); гипоплазия поджелудочной железы с или без экзокринной недостаточности; холестаз в неонатальном периоде; асимптоматическое повышение уровня печеночных ферментов; различные пороки развития половой системы, а также неврологическая симптоматика. Мультисистемность поражения при HNF1β-ассоциированном заболевании крайне затрудняет клиническую верификацию диагноза. В настоящей статье мы приводим клиническое наблюдение за пациентом, у которого первыми клиническими проявлениями HNF1β-ассоциированного заболевания были УЗ-изменения почек (гиперэхогенные почки?), выявленные еще в период внутриутробного развития, а в первые дни жизни, по данным УЗИ, диагностирован поликистоз почек. Уже на первом году жизни у ребенка имело место снижение функции почек, развился синдром Фанкони в виде глюкозурии, низкомолекулярной протеинурии, гипофосфатемии, аминоацидурии, гиперурикозурии, а также повышение экскреции с мочой магния. К трем годам, по данным УЗИ, кроме поликистоза почек с увеличением размеров кист в динамике, был диагностирован двусторонний медуллярный нефрокальциноз 1 степени; а также наблюдались непостоянное асимптоматическое повышение уровня печеночных ферментов, гиперпаратиреоз, остеопороз. Учитывая широкий спектр клинической симптоматики, верифицировать диагноз удалось только благодаря результатам молекулярно-генетического исследования, выявившего не описанную ранее гетерозиготную мутацию в 4 экзоне гена HNF1b (chr17:36091813C&gt;T), p.Cys273Tyr (c.818G&gt;A). Выявленная мутация была валидирована секвенированием по Сенгеру. У родителей ребенка секвенирование по Сенгеру не выявило мутации chr17:36091813C&gt;T, что позволило предположить появление мутации у ребенка de novo.</p></abstract><trans-abstract xml:lang="en"><p>Hepatocyte nuclear factor 1β (HNF1β)-associated disease is a rare autosomal dominant disease caused by various mutations in the HNF1β gene coding the hepatocyte nuclear factor 1β. HNF1β is a transcription factor that is critical for the development of kidney urogenital tract, pancreas, liver, brain, and parathyroid gland. Renal phenotype or HNF1β- nephropathy appeared to be extremely heterogenic: multicystic renal dysplasia, renal hypoplasia, unilateral renal agenesis, horseshoe kidney, atypical familial juvenile hyperuricemic nephropathy, urinary tract malformations and tubular dysfunction. Extrarenal phenotype of HNF1β-associated disease could be maturity-onset diabetes of the young (MODY), pancreatic atrophy and exocrine pancreatic dysfunction, elevated liver enzymes, neonatal cholestasis, congenital abnormalities of the genital tract, hyperparathyroidism, neurological symptoms. The multisystem phenotype makes clinical verification of the diagnosis extremely difficult. In this article, we present a clinical observation of a child with HNF1β – associated disease. The first clinical presentation of HNF1β-associated disease was ultrasound changes in the kidneys (hyperechogenic kidneys?), which were detected by prenatal ultrasonography in pregnancy. Renal ultrasound revealed polycystic kidney disease in the first days of life and bilateral medullary nephrocalcinosis by the age of three. The clinical examination showed a reduced renal function and developed Fanconi syndrome (glycosuria, low molecular proteinuria, hypophosphatemia, aminoaciduria, hyperuricosuria) in the first year of life. Also the child had a non-constant asymptomatic elevation of liver enzymes, hyperparathyroidism, osteoporosis. The diagnosis was confirmed by the results of next generation sequencing which revealed novel heterozygous mutation in exon 4 of the HNF1b gene (chr17: 36091813C&gt;T), p.Cys273Tyr (c.818G&gt;A). The identified mutation was validated by Sanger sequencing. Validation by Sanger sequencing did not reveal a chr17: 36091813C&gt;T mutation in parents, which suggested the appearance of a mutation in the child de novo.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>HNF1β-ассоциированное заболевание</kwd><kwd>поликистоз почек</kwd><kwd>почечная недостаточность</kwd><kwd>дети</kwd></kwd-group><kwd-group xml:lang="en"><kwd>HNF1β-associated disease</kwd><kwd>polycystic kidney disease</kwd><kwd>kidney failure</kwd><kwd>children</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">Horikawa Y, Iwasaki N, Hara M, Furuta H et al.
