It is conventionally subdivided into total (the absence of commissural fibers) and partial (agenesis of the rostral and caudal areas of the corpus callosum) ACC. The disorder can either be individual or associated with other developmental brain malformations. Isolated pathologies of the corpus callosum can be clinically occult, thus significantly impeding diagnosis of this pathology. AAC can be verified using various neuroimaging data, including fetal brain ultrasonography. In this study, we report two cases of patients with ACC associated with hereditary syndromes from our own clinical experience. In one case, the course of the disease was relatively favorable. The severe infantile form with fatal outcome is reported in the second case. The detailed autopsy data and results of morphological examination of the brain are presented. Special attention is paid to the issues associated with analysis of clinical phenotypes, as well as lifetime and postmortem diagnosis of the disease.</p></abstract><trans-abstract xml:lang="ru"><p>Агенезия мозолистого тела (АМТ) обнаруживается при церебральных дисгенезиях, ассоциированных с различными наследственными синдромами. Она традиционно подразделяется на тотальную (отсутствуют комиссуральные волокна) и парциальную (агенезия ростральных и каудальных отделов мозолистого тела). АМТ может встречаться изолированно или в сочетании с другими пороками развития головного мозга. Изолированные нарушения мозолистого тела клинически могут не проявляться, что значительно затрудняет своевременную диагностику данной патологии. Наличие АМТ может быть подтверждено данными различных методов нейровизуализации, включая пренатальное ультразвуковое исследование головного мозга. В настоящей статье приведены два собственных клинических наблюдения пациентов с АМТ, ассоциированной с наследственными синдромами. В одном случае имело место относительно благоприятное течение заболевания, в другом – описана тяжелая младенческая форма с летальным исходом, с представлением детальных данных аутопсии и морфологического исследования мозга. Особое внимание уделено вопросам анализа клинических фенотипов, прижизненной и постмортальной диагностике болезни.</p></trans-abstract><kwd-group xml:lang="en"><kwd>agenesis</kwd><kwd>corpus callosum</kwd><kwd>clinical manifestation</kwd><kwd>hereditary syndromes</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>агенезия</kwd><kwd>мозолистое тело</kwd><kwd>клиническая манифестация</kwd><kwd>наследственные синдромы</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Stevenson R.E., Hall J.G.
