Sequencing Study Links Mutations in Major Heart Muscle Protein to Development of Dilated Cardiomyopathy

British heart disease researchers using advanced gene sequencing techniques have identified mutations in the TTN gene, which encodes the muscle protein titin, linked to development of dilated cardiomyopathy that are different from benign mutations in this gene that are carried by a large percentage of the population.  More...
