dc.description.abstractAdvances in human genome sequencing have re-invigorated genetics studies of dilated cardiomyopathy (DCM), facilitating genetic testing and clinical applications. With a range of genetic testing options now available, new challenges arise for data interpretation and identifying single pathogenic variants from the many thousands of rare variants present in every individual. There is accumulating evidence that genetic factors have an important role in the pathogenesis of DCM. However, although more than 100 genes have been implicated to date, the sensitivity of genetic testing, even in familial disease, is only ∼25-40%. As more patients are genotyped, nuanced information about disease phenotypes is emerging including variability in age of onset and penetrance of DCM, as well as additional cardiac and extra-cardiac features. Genotype-phenotype correlations have also identified a subset of genes that can be highly arrhythmogenic or show frequent progression to heart failure. Recognition of variants in these genes is important as this may impact on the timing of implantable cardioverter-defibrillators or heart transplantation. Finding a causative variant in a patient with DCM allows predictive testing of family members and provides an opportunity for preventative intervention. Diagnostic imaging modalities such as speckle-tracking echocardiography and cardiac magnetic resonance imaging are increasingly being used to detect and monitor pre-clinical ventricular dysfunction in asymptomatic variant carriers. Although there are several examples of successful genotype-based therapy, optimal strategies for implementation of precision medicine in familial DCM remain to be determined. Identification of modifiable co-morbidities and lifestyle factors that exacerbate or protect against DCM development in genetically-predisposed individuals remains a key component of family management.
