Мутации в гене STRC – вторая основная причина врожденной двусторонней тугоухости легкой или умеренной степени после мутаций в гене GJB2.</p></sec><sec><title>Цель</title><p>Цель: оценить распространенность аутосомно-рецессивной формы DFNB16, данные анамнеза и результаты аудиологического обследования детей с мутациями в гене STRC.</p></sec><sec><title>Методы</title><p>Методы. Анализ амбулаторных карт детей с 2008 по 2023 г.р., состоящих на диспансерном учете в Городском детском консультативно-диагностическом сурдологическом центре, осмотр, аудиологическое и оториноларингологическое обследование, анализ результатов генетических исследований.</p></sec><sec><title>Результаты</title><p>Результаты. Проанализированы амбулаторные карты 1256 детей с двусторонней тугоухостью I и II степени. Генетическое обследование проведено 540 детям (43%). В этой группе мутации в гене GJB2 были подтверждены у 44% обследованных, в гене STRC – у 8%, в гене USH2A – у 2%. Возраст детей с DFNB16 при первичном обращении к сурдологу составил 48 месяцев. Аудиологический скрининг в роддоме «не прошли» 50% детей, 30% имели результат «прошел», и в 20% случаев скрининг в роддоме не проводился. По данным первичной тональной пороговой аудиометрии средний порог слуха на частотах 0,5-4 кГц составил 45,8 дБ, при повторном обследовании – 42,8 дБ.</p></sec><sec><title>Выводы</title><p>Выводы. Рецессивная форма DFNB16 в обследованной группе детей с легкой или умеренной степенями тугоухости подтверждена в 8% случаев. Наличие сопутствующей патологии ЛОР-органов увеличивает возраст обращения к сурдологу и проведения генетических исследований.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Mutations in the STRC gene are the second main cause of congenital bilateral mild to moderate hearing loss after mutations in the GJB2 gene.</p></sec><sec><title>Objective</title><p>Objective: to assess the prevalence of the autosomal recessive form of DFNB16, medical history and results of audiological examination in children with mutations in the STRC gene.</p></sec><sec><title>Methods</title><p>Methods. Analysis of medical records of children born between 2008 and 2023, registered at the children’s audiological center, audiological and otolaryngological examination, analysis of the results of genetic studies.</p></sec><sec><title>Results</title><p>Results. Medical records of 1256 children with bilateral hearing loss of I and II degrees were analyzed. Genetic examination was performed on 540 children (43%). In this group, mutations in the GJB2 gene were confirmed in 44% of the examined patients, in the STRC genein 8%, in the USH2A gene – in 2%. The median age of children with DFNB16 at the initial visit to an audiologist was 48 months. 50% of children «failed» the hearing screening, 30% had the result «passed», and in 20% of cases, screening in the maternity hospital was not performed. According to the initial tonal threshold audiometry, the average hearing threshold at frequencies of 0.5-4 kHz was 45.8 dB, during the repeated examination – 42.8 dB.</p></sec><sec><title>Conclusions</title><p>Conclusions. DFNB16 occurs in 8% of cases among children with mild to moderate bilateral sensorineural hearing loss. The presence of concomitant ENT pathology increases the average age of contacting an audiologist and conducting genetic studies.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>врожденная тугоухость легкой и умеренной степени</kwd><kwd>DFNB16</kwd><kwd>аутосомно-рецессивная тугоухость</kwd><kwd>STRC</kwd><kwd>GJB2</kwd></kwd-group><kwd-group xml:lang="en"><kwd>congenital mild to moderate hearing loss</kwd><kwd>DFNB16</kwd><kwd>autosomal recessive deafness-16</kwd><kwd>STRC</kwd><kwd>GJB2</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено без спонсорской поддержки.</funding-statement><funding-statement xml:lang="en">The study was not supported by sponsorship.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Sloan-Heggen C.O., Bierer A.O., Shearer A.E.
