Представлено описание клинического случая семейной ассоциированной с мутацией в гене LMNA кардиомиопатии, диагноз которой верифицирован с помощью полногеномного секвенирования. Наличие клинического сценария, характерного для ламинассоциированной кардиомиопатии, свидетельствует о патогенном характере мутации в экзоне 1 гена LMNA, ранее считавшейся мутацией с неизвестным клиническим значением. Приведенный клинический случай демонстрирует кардинальное изменение стратегий лечения пациентов в условиях широкого внедрения в практику молекулярно-генетических методов исследования.
We present a clinical case of familial LMNA-associated cardiomyopathy, confirmed by whole genome sequencing. The typical for lamin-associated cardiomyopathy indicates pathogenic nature of the mutation in the first exon of LMNA gene, previously considered a mutation of unknown clinical significance. The presented clinical case demonstrates a radical change in patient treatment strategies in the context of the widespread introduction of molecular genetic research methods into practice.
