В некоторых случаях плечи могут быть увеличены из-за несбалансированной транслокации с участием гетерохроматина, чаще всего Yq. Данный феномен может быть объяснен ассоциацией этих хромосом с комплексом ХY в стадии ранней пахитены. Носители несбалансированных Y-аутосомных транслокаций обычно имеют нормальные фенотип и фертильность. Однако в некоторых сообщениях было показано, что носители t (Y;15)(q12;p11) могут иметь репродуктивные проблемы или рождение детей с аномальным фенотипом. При использовании молекулярно-цитогенетических методов была дана подробная характеристика гетероморфизма гомологов акроцентрических хромосом в четырех случаях увеличенного гетерохроматина коротких плеч хромосомы 14 и 15. FISH-анализ позволил определить несбалансированную транслокацию Y;15 в трех случаях, и Y;14 - в одном. Информация о вариантах гетерохроматиновых районов хромосом позволяет обеспечить соответствующее медико-генетическое консультирование семьи.</p></abstract><trans-abstract xml:lang="en"><p>Chromosomal heteromorphism, in the form of increasing of the short arms of acrocentric chromosomes, is quite common in cytogenetic diagnosis. In some cases, these may be increased due to unbalanced translocation involving heterochromatin, most often Yq. This phenomenon can be explained by the association of these chromosomes with the XY complex in early pachytene. Carriers of unbalanced Y-autosomal translocations usually have a normal phenotype and fertility. However, in some reports, it has been shown that carriers t (Y; 15) (q12; p11) may have reproductive problems or children with abnormal phenotype. When using molecular cytogenetic methods, a detailed characterization of heteromorphism of acrocentric chromosomes was given in four cases. FISH analysis allowed us to determine the unbalanced translocation Y;15 in three cases, and Y;14 - in one. Information on the variants of heterochromatin chromosome regions allows to provide appropriate medical-genetic counseling to the family.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гетероморфизм хромосом</kwd><kwd>Y-аутосомные транслокации</kwd><kwd>флуоресцентная in situ гибридизации (FISH)</kwd><kwd>Chromosomal heteromorphisms</kwd><kwd>Y-autosome translocations</kwd><kwd>fluorescence in situ hybridization (FISH)</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">Liehr T.
