В работе приведены клинические наблюдения, а также результаты гормональных и молекулярных исследований 6 пациентов с дефицитом Р450с17. Все больные имели женский фенотип при рождении, у 5 был мужской кариотип, у 1 - женский. Первоначально у всех генетических мужчин был ошибочно поставлен диагноз синдрома тестикулярной феминизации, тогда как 1 генетическая женщина наблюдалась по поводу недостаточности яичников. Тяжелая артериальная гипертензия (до 200/130 мм рт. ст.) наблюдалась в 5 из 6 случаев. Гипокалиемия отмечалась у 3 больных. Дефицит Р450с17 был установлен на основании повышения уровня кортикостерона в сыворотке, а у 4 пациентов подтвержден также данными мультистероидного анализа. При амплификации и последующем прямом секвенировании гена СУР 17у 1 больного была выявлена гомозиготная мутация в экзоне 1 (R96Q). В 2 неродственных друг другу семьях (4 пациента) была обнаружена одинаковая мутация в экзоне 6 (V360L). Наконец, у 1 больного была выявлена составная гетерозиготность по 2 мутациям: в экзоне 6 (R347C) и экзоне 8 (R416C). Данные наблюдения подчеркивают необходимость дифференциальной диагностики дефицита Р450с17 и синдрома тестикулярной феминизации.</p></abstract><trans-abstract xml:lang="en"><p>Deficiency of Р450с17 (17a-hydroxylase/17,20-liase) is а rare hereditary steroidogenesis defects disordering the synthesis of sex steroids and leading to excessive production of mineralocorticoid production. Clinical findings and results of molecular and hormonal studies in 6patients with P450cl7 deficiency are presented. All patients were born with female phenotype, 5 with male karyotype and 1 with female karyotype. Testicular feminization was erroneously diagnosed in all genetic men, and the genetic woman was treated for ovarian in sufficiency. Five of 6 patients suffered from severe arterial hypertension (up to 100/130 mm Hg). Hypopotassemia was observed in 3 patients. P450cl7 deficiency was diagnosed on the basis of increased serum corticosterone level, and in 4 patients it was confirmed by multisteroid analysis. Amplification and subsequent direct sequencing of CYP17gene revealed homozygotic mutation in exon 1 (R96Q) in 1 patient. The same mutations in exon 6 (V360L) were detected in 2 unrelated families (4 patients). Constituent heterozygosis by 2 mutations, in exon 6 (R347C) and exon 8 (R416C), was detected in 1 patient. These findings evidence the need in differential diagnosis of P450cl7 deficiency and the testicular feminization syndrome.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Клиническая</kwd><kwd>гормональная и молекулярно-генетическая характеристика</kwd><kwd>дефицит Р450с 17</kwd><kwd>синдром тестикулярной феминизации</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Clinical</kwd><kwd>hormonal</kwd><kwd>and molecular genetic characteristics</kwd><kwd>deficiency of Р450с17</kwd><kwd>testicular feminization syndrome</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">Тюльпаков А.
