Делеции в локусе 1q23q25 вызывают отличительный фенотип, включающий пропорциональный низкий рост, микроцефалию, брахидактилию, дисморфические черты лица и умственную отсталость. Другие, реже описываемые признаки, включают почечные, сердечные и генитальные пороки развития, краниосиностоз и одинарную ладонную складку.Цель: выявить и охарактеризовать новую делецию в локусе 1q24.3q25.3 у пробанда с дефицитом гормона роста и естественных антикоагулянтов.Методы. Пробанд 7-летняя девочка с пропорциональной задержкой внутриутробного развития, врожденными пороками сердца, а также гиперфибриногенемией и дефицитом антитромбина III. Единственный случай в семье. Дифференциальные диагнозы включали микрохромосомную патологию и акромелическую дисплазию. Было проведено секвенирование полного генома матери и пробанда. Отец отказался от любых исследований.Результаты. У пробанда зарегистрирована делеция в гетерозиготном состоянии в локусе 1q24.3q25.3, которая составляет около 9,232 млн п.н.. Эта делеция включает следующие гены с аутосомно доминантным типом наследования: LHX4, SERPINC1, XPR1, MYOC, FASLG.Заключение. В ходе исследования выявлена уникальная делеция длинного плеча хромосомы 1. Эта новая делеция является первым идентифицированным случаем синдрома делеции в локусе 1q23q25 в России и объясняет причину низкого роста, лицевых дисморфий и тромбофилии у пробанда. Раннее распознавание этого синдрома и проактивное вмешательство могут улучшить качество жизни пациента.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. Deletions at the 1q23q25 locus cause a distinctive phenotype including proportionate short stature, microcephaly, brachydactyly, dysmorphic facial features, and intellectual disability. Other less commonly reported features include renal, cardiac and genital malformations, craniosynostosis, and single palmar crease.Objective. To identify and characterize a novel deletion at the 1q24.3q25.3 locus in a proband with growth hormone deficiency and natural anticoagulant deficiency.Methods. The proband was a 7-year-old girl with proportionate intrauterine growth retardation, congenital heart defects, hyperfibrinogenemia and antithrombin III deficiency. The only case in the family. Differential diagnoses included microchromosomal pathology and acromelic dysplasia. Whole genome sequencing was performed for the mother and proband. The father is categorically against any research.Results. The proband has a heterozygous deletion at the 1q24.3q25.3 locus, which is about 9.232 Mb. This deletion includes the following genes with an autosomal dominant type of inheritance: LHX4, SERPINC1, XPR1, MYOC, FASLG.Conclusions. The study identified a deletion of the long arm of chromosome 1. This new mutation is the first identified case of a deletion syndrome at the 1q23q25 deletion locus in Russia and is the cause of short stature, facial dysmorphia, and thrombophilia in the proband. Early detection of this syndrome and proactive intervention may improve quality of life.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>1q24.3q25.3</kwd><kwd>LHX4</kwd><kwd>дефицит гормона роста</kwd><kwd>SERPINC1</kwd><kwd>дефицит анитромбина III</kwd><kwd>микроделеционный синдром</kwd></kwd-group><kwd-group xml:lang="en"><kwd>1q24.3q25.3</kwd><kwd>LHX4</kwd><kwd>growth hormone deficiency</kwd><kwd>SERPINC1</kwd><kwd>anthrombin III deficiency</kwd><kwd>microdeletion syndrome</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено в рамках государственного задания Министерства науки и высшего образования.</funding-statement><funding-statement xml:lang="en">The study was carried out on the state assignment of the Ministry of Science and Higher Education.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Radovick S., Nations M., Du Y. et.al.
