While the total cohort was modest (n = 66), the study expanded the genes associated with cardiomyopathy by identifying causative variants in genes previously associated with arrhythmia (CALM1), genes associated with heart development, and genes (PPA2, NRAP) that may be susceptibility factors for cardiomyopathy in combination with environmental triggers such as viral infection. The gene discussed is CALM1; the disease is cardiomyopathy.
