Около 85 % пациентов имеют кариотип 47,XXY, остальные — другие цитогенетические варианты синдрома Клайнфельтера. В статье описан клинический случай синдрома Клайнфельтера с двойной Y-аутосомной транслокацией. Пробанд — 15-летний пациент мужского пола (рост 180 см, масса тела 50 кг, нормальный IQ), направленный на медико-генетическое обследование и консультирование в связи с задержкой полового созревания. У пациента диагностированы гипоплазия яичек, гипергонадотропный гипогонадизм, микроаденома гипофиза и левостороннее варикоцеле. Пробанд родился в неродственном браке после процедуры экстракорпорального оплодотворения, выполненной из-за мужского бесплодия у отца. Хромосомный анализ проводили на культивированных лимфоцитах периферической крови с помощью стандартного цитогенетического метода с использованием GTG-окрашивания и FISH-анализа. Молекулярный анализ Y-хромосомы выполняли методом мультиплексной ПЦР. Комплексное цитогенетическое исследование выявило у пробанда кариотип 46,XX,der(Y)t(Y;15)(q12;q11.1),der(13)t(Y;13) (q12;p11.2),-15. Молекулярный анализ показал, что пробанд является SRY-положительным; микроделеции Y-хромосомы не обнаружены. У отца пробанда диагностирована олигозооспермия и наличие робертсоновской транслокации (13;15) — 45,XY,der(13;15)(q10;q10), у матери выявлен нормальный женский кариотип (46,XX). Очевидно, что дериватные хромосомы der(13) и der(Y) возникли в результате аномальной мейотической рекомбинации в отцовском мейозе между гетерохроматической областью Yq12 и центромерным/перицентромерным гетерохроматином хромосом 13 и 15, вовлеченных в робертсоновскую транслокацию у отца, а синдром Клайнфельтера обусловлен наличием в кариотипе двух Х-хромосом в присутствии дериватной Y-хромосомы. Обнаруженная двойная Y-аутосомная транслокация является независимой от синдрома Клайнфельтера хромосомной аномалией, возникшей на фоне робертсоновской транслокации у отца.</p></abstract><trans-abstract xml:lang="en"><p>   Klinefelter syndrome is one of the most common chromosomal abnormalities and the most common genetic cause of male infertility. About 85 % of patients have 47,XXY karyotype, other patients have other non-mosaic and mosaic Klinefelter syndrome variants. We report a unique clinical case — Klinefelter syndrome patient with double Y autosomal translocation. The proband is a 15-year-old male patient (height 180 cm, weight 50 kg, normal IQ) who was admitted for cytogenetic examination and genetic counseling due to delayed puberty. He was diagnosed with testicular hypoplasia, hypergonadotropic hypogonadism, pituitary microadenoma and left-sided varicocele. The proband was born in a nonconsanguineous marriage after in vitro fertilization due to paternal male factor infertility. Cytogenetic analysis was performed on cultured peripheral blood lymphocytes using standard chromosome analysis with GTG staining and FISH analysis. Molecular analysis of the Y chromosome was performed by multiplex PCR. Complex cytogenetic examination revealed a 46,XX,der(Y) t(Y;15)(q12;q11.1),der(13)t(Y;13)(q12;p11.2),-15 karyotype in the proband. Molecular analysis showed that the proband is SRY positive; no microdeletion of the Y chromosome was found. The detected double Y autosomal translocation is a chromosomal abnormality independent of KS. The father of the proband is an oligozoospermic man with robertsonian translocation 13;15 — 45,XY,der(13;15)(q10;q10), the mother has a normal karyotype 46,XX. Apparently, the der(13) and der(Y) chromosomes result from abnormal meiotic recombination in paternal meiosis between the heterochromatic region Yq12 and the centromeric/pericentromeric heterochromatin of chromosomes 13 and 15 involved in the paternal robertsonian translocation, and Klinefelter syndrome is due to the presence of two X chromosomes in the karyotype in the presence of a derivative Y chromosome. The detected double Y-autosomal translocation is a chromosomal abnormality unrelated to Klinefelter syndrome, arising on the background of the paternal robertsonian translocation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>половые хромосомы</kwd><kwd>синдром Клайнфельтера</kwd><kwd>робертсоновские транслокации</kwd><kwd>Y-аутосомные транслокации</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>sex chromosomes</kwd><kwd>Klinefelter syndrome</kwd><kwd>robertsonian translocations</kwd><kwd>Y-autosomal translocations</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания Минобрнауки России для ФГБНУ «МГНЦ».
