LONDON (Reuters) - Scientists have identified the crucial genetic mutations that cause a common heart condition called dilated cardiomyopathy (DCM), paving the way for more accurate diagnosis and screening of high-risk patients.

In a study of more than 5,000 people, researchers sequenced the gene encoding the muscle protein "titin", known to be linked to this leading cause of inherited heart failure, to try to find which variations in it caused problems.
