These observations are of professional and scientific interest, since they relate to rare neurological pathology. The rarity of this anomaly, the presence of complications, the high cost of invasive diagnostics, the variability of the phenotype, including severe congenital malformations in children with microdeletions lead together to underdiagnosis of patients at the stage of prenatal diagnostics, which entails difficulties in selecting effective and safe therapy, a need for medical and psychosocial rehabilitation of children in society. In case of refractory epilepsy with developmental delay in infancy, typical to chromosomal microdeletions, genetic counseling and examination should be carried out to search for chromosomal pathology. Increasing the awareness of doctors about this disorder will contribute to its timely diagnostics and treatment.</p></abstract><trans-abstract xml:lang="ru"><p>В статье описаны три клинических случая наследственных нарушений, связанных с хромосомными мутациями: делециями хромосом 14 и 18. Эти наблюдения представляют профессиональный и научный интерес, т.к. относятся к раритетной неврологической патологии. Редкость данной аномалии, наличие осложнений, дороговизна инвазивной диагностики, вариабельность фенотипа, включая тяжелые врожденные пороки развития у детей с микроделециями, – все это приводит к недодиагностированию пациентов на этапе пренатальной диагностики, что влечет за собой трудности в подборе эффективной и безопасной терапии, потребность в медицинской и психосоциальной реабилитации детей в обществе. При возникновении рефрактерной эпилепсии с задержкой развития в младенческом возрасте, характерной для хромосомных микроделеций, следует проводить генетическое консультирование и обследование с целью поиска хромосомной патологии. Повышение осведомленности врачей о данном нарушении будет способствовать его своевременным диагностике и лечению.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>хромосомные заболевания</kwd><kwd>делеции</kwd><kwd>кольцевая хромосома</kwd><kwd>резистентная эпилепсия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chromosomal diseases</kwd><kwd>deletions</kwd><kwd>ring chromosome</kwd><kwd>resistant epilepsy</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">Камалтынова Е.М., Салюкова О.А., Федорова О.С. и др.
