LMNA and atrial fibrillation: Atrial fibrillation (AF) can be associated with a genetic predisposition, particularly in younger individuals without common risk factors.1,2 Familial laminopathies are well known for cardiac involvement, with heart failure as well as atrial and ventricular arrhythmias as the main manifestations.1,2 We describe the clinical presentation and management of atrial arrhythmias in a family with LMNA mutation, highlighting the importance of genetic counselling and surveillance in hereditary cardiac conditions.
