Impaired Reorganization of Centrosome Structure Underlies Human Infantile Dilated Cardiomyopathy

The article discusses a study that investigated the role of centrosome reduction, a process where the components of the centrosome reorganize during cardiomyocyte maturation. The study found that disruption of this process, caused by a genetic defect in the RTTN gene, can result in infantile dilated cardiomyopathy. The study used induced pluripotent stem cells, whole exome sequencing, and in vivo models to identify and validate the causal gene. The study also identified a potential therapeutic strategy for this type of cardiomyopathy. This research provides insight into the role of centrosome reduction in cardiac development and may lead to the discovery of additional contributors to human cardiac disease.
