ВА характеризуется врожденным отсутствием радужной оболочки глаза или врожденной гипоплазией большей ее части. ВА может быть: несиндромальной, которая, однако, часто затрагивает все структуры глаза (75 % случаев) и синдромальной (20%, включая WAGR синдром). Часть форм ВА, как изолированной, так и синдромальной, обусловлена гетерозиготными мутациями в гене PAX6 и хромосомными перестройками, вовлекающими регион 11p13. Делеции в том же регионе, но с вовлечением, помимо гена PAX6, еще и гена WT1 приводят к синдрому WAGR. В исследование включены 110 пациентов с предположительным диагнозом изолированная врожденная аниридия из 84 неродственных семей и 7 пациентов из 7 неродственных семей - с диагнозом синдром WAGR . Применяемая комплексная подтверждающая и дифференциальная ДНК-диагностика ВА и синдрома WAGR состоит из двух основных последовательных этапов: MLPA анализа (с подтверждением обнаруженных делеций с помощью анализа потери гетерозиготности или FISH) и секвенирования по Сэнгеру. Эффективность применения MLPA-анализа в качестве первоначального метода диагностики составляет 33% (30/91). Эффективность применения секвенирования в качестве единственного метода диагностики ВА вне предлагаемой комплексной технологии в выборке российских больных составила бы 63,7% (58/91). В результате использования предлагаемой технологии диагноз подтвержден у 107 пациентов (81 пробанда) с несиндромальной ВА и 7 пациентов с синдромом WAGR, определены частые в выборке пациентов из России PAX6 мутации. Эффективность применения двух последовательных этапов комплексной технологии подтверждающей и дифференциальной диагностики ВА в выборке пациентов из России составила 96,7% (88/91).</p></abstract><trans-abstract xml:lang="en"><p>Congenital aniridia is a Mendelian autosomal dominant panocular disorder with complete penetrance and variable expressivity. The incidence of aniridia is 1 in 40,000-100,000 births. Aniridia is characterized by congenital absence of the iris with foveal hypoplasia and other eye abnormalities. Aniridia occurs as non-syndromic which, however, often affects all eye structures (75% of cases) and syndromic (20%, including WAGR syndrome). The most cases of aniridia, both isolated and syndromic, is caused by heterozygous mutations in the PAX6 gene or chromosome 11p13 rearrangements. Large deletions of the same region affecting PAX6 and WT1 genes loci lead to the WAGR syndrome. 110 patients with a preliminary diagnosis of congenital aniridia from 84 unrelated families and 7 patients from 7 unrelated families diagnosed with WAGR syndrome were included into the study. The applied complex confirmatory and differential DNA diagnosis of aniridia and WAGR syndrome consists of two main sequential steps: MLPA analysis (with confirmation of the detected deletions using the loss of heterozygosity analysis and/or FISH) and Sanger sequencing. The efficiency of MLPA analysis as an initial diagnostic method is 33% (30/91). The effectiveness of sequencing as the only method for diagnosis of aniridia is 63.7% (58/91). As a result of the application of complex medical technology at the Research Centre for Medical Genetics, the diagnosis was confirmed in 107 patients (81 probands) with aniridia and 7 patients with WAGR syndrome. Frequent PAX6 mutations and 11p13 deletions were identified. The effectiveness of two-staged technology for congenital aniridia diagnosis is 96.7% (88/91).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>врожденная аниридия</kwd><kwd>синдром WAGR</kwd><kwd>PAX6</kwd><kwd>MLPA</kwd><kwd>11p13</kwd><kwd>внутригенные мутации</kwd><kwd>крупные хромосомные делеции</kwd><kwd>congenital aniridia</kwd><kwd>WAGR syndrome</kwd><kwd>PAX6</kwd><kwd>MLPA</kwd><kwd>11p13</kwd><kwd>intragenic mutations</kwd><kwd>large chromosome deletions</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">Hingorani, M., I.
