Genetic Arrhythmias Complicating Patients with Dilated Cardiomyopathy: How it happens.

In this edition of the Journal, Li et al report on patients with dilated cardiomyopathy (DCM) and arrhythmias (DCM-A) compared with patients with DCM with no arrhythmias (DCM-NA), with the explicit intent to identify the genetic causes of arrhythmias in DCM.1 Using whole-exome sequencing and high-depth targeted next-generation sequencing followed by Sanger sequencing of all causative variants to eliminate false-positive results, eight specific DCM-A pedigrees and two separate cohorts of 1232 consecutive unrelated sporadic DCM-NA patients were studied (550 patients in discovery cohort, 682 patients in replication cohort).
