Dilated Cardiomyopathy Due to BLC2-Associated Athanogene 3 (BAG3) Mutations

The BAG3 (BLC2-associated athanogene 3) gene codes for an antiapoptotic protein located on the sarcomere Z-disc. Mutations in BAG3 are associated with dilated cardiomyopathy (DCM), but only a small number of cases have been reported to date, and the natural history of BAG3 cardiomyopathy is poorly understood. This study sought to describe the phenotype and prognosis of BAG3 mutations in a large multicenter DCM cohort. The study cohort comprised...
