| Outline of Final Research Achievements |
We performed comprehensive genetic analysis of genes that would cause dilated cardiomyopathy (DCM) in sudden death with cardiomyopathies or concentric/dilatation hypertrophy. DCM-associated mutation was detected from one HCM case in LDB3 and other HCM case in RBM20. These HCM cases also had a mutation associated with HCM in other gene. In addition, a novel mutation was detected from one concentric hypertrophy case in RBM20. This mutation was located near to the mutation associated with HCM. These results suggested that multiple gene mutations associated with each cardiomyopathy would exacerbate cardiac function and RBM20 might be not only as DCM-causing gene but also as HCM-causing gene. Further investigation using more postmortem samples is need for proving this hypothesis and elucidating the molecular mechanism in the onset of cardiomyopathy.
