This reveals that the LMNA gene insertion mutation (T510Y frameshift mutation) can cause dilated cardiomyopathy, conduction system disease, and sudden cardiac death without skeletal myopathy, clinically manifested with early onset, severe symptoms, and poor prognosis.
Mutations in the lamin A/C gene (LMNA) have been reported to be involved in dilated cardiomyopathy (DCM) associated with conduction system disease and/or skeletal myopathy.
