Dilated cardiomyopathy is a disorder characterised by cardiac enlargement (especially of the left ventricle), poor myocardial contractility, and congestive heart failure. This test detects a DNA variant that is linked to this phenotype.
Clinical signs include enlargement of the heart, shortness of breath, angina and syncope.
This test is based on a genome wide association study. There is no causality shown between the disease and DNA variant. Further research needs to be performed to prove this causality.
