Syndrome associated with dilated cardiomyopathy

Syndrome associated with dilated cardiomyopathy (Orphanet code 217619) is a broad classification category in Orphanet that encompasses a group of genetic syndromes in which dilated cardiomyopathy (DCM) is a prominent clinical feature occurring alongside other systemic manifestations. Dilated cardiomyopathy is characterized by enlargement and weakening of the heart's left ventricle (or both ventricles), leading to impaired pumping function. When DCM occurs as part of a syndrome, it is accompanied by additional features affecting other organ systems, which may include skeletal muscle weakness, neurological abnormalities, metabolic disturbances, hearing loss, facial dysmorphism, or other congenital anomalies depending on the specific underlying syndrome. Because this Orphanet entry represents a grouping category rather than a single discrete disease entity, the specific clinical presentation, genetic cause, inheritance pattern, and prognosis vary considerably depending on the individual syndrome involved. Examples of syndromes that fall under this umbrella include Barth syndrome, certain mitochondrial disorders, muscular dystrophies with cardiac involvement (such as Duchenne or Emery-Dreifuss muscular dystrophy), and various other multisystem genetic conditions. Management typically involves standard heart failure therapies including ACE inhibitors, beta-blockers, diuretics, and in severe cases, cardiac transplantation, alongside syndrome-specific treatments addressing the other affected organ systems. Genetic counseling is recommended for affected families to clarify the specific diagnosis and recurrence risk.
