Мутации в гене коннексина 50 (GJA8) относятся к частым причинам наследственных, преимущественно аутосомно-доминантных, врожденных катаракт. У пациента с врожденной двусторонней зонулярной катарактой в гене GJA8 идентифицированы две нуклеотидные замены в компаунд-гетерозиготном состоянии - ранее не описанный миссенс-вариант с.143A&gt;G (p.Glu48Gly) и известный нуклеотидный вариант с.741Т&gt;G (p.Ile24Met). На основании клинико-генеалогического и молекулярно-генетического анализа установлен спорадический характер заболевания в семье. Впервые выявленный вариант p.Glu48Gly, предположительно, является патогенной мутацией, проявляющей рецессивный характер.</p></abstract><trans-abstract xml:lang="en"><p>Significant clinical and genetic heterogeneity of hereditary cataracts significantly complicates their early DNA diagnosis and determines the relevance of studying the epidemiology of the disease, population features of the spectrum and frequencies of mutations in responsible genes, clinical and genetic correlations. Mutations in the connexin 50 (GJA8) gene are common causes of hereditary, mainly autosomal dominant, congenital cataracts. In a patient with congenital bilateral zonular cataract in the GJA8 gene two nucleotide substitutions were identified in the compound heterozygous state - the previously undescribed missense variant C.143A&gt;G (p.Glu48Gly) and the known nucleotide variant C.741T&gt;G (p.Ile24Met). Based on clinical genealogical and molecular genetic analysis, the sporadic nature of the disease in the family was established. The newly identified variant of p.Glu48Gly is presumably a pathogenic mutation showing a recessive character.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>врожденная наследственная катаракта</kwd><kwd>коннексин 50</kwd><kwd>GJA8</kwd><kwd>мутации</kwd></kwd-group><kwd-group xml:lang="en"><kwd>congenital hereditary cataract</kwd><kwd>connexin 50</kwd><kwd>GJA8</kwd><kwd>mutations</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">Goodenough D.A., Goliger J.A., Paul D.L.
