DSC2 and dilated cardiomyopathy: The genetic test also included a search for mutations in the PLN, TMEM43, KCNJ2, CASQ2, CTTNNA3, DES, DSC2, DSG2, DSC2, JUP, PKP2 and LMNA genes, and the entire panel of dilated cardiomyopathy-related genes, which were, however, found to be normal, except for a mutation of uncertain significance in the JUP gene in only one of the three offspring.
