Background and aim: The DSP gene (locus. 6p24.3) encodes desmoplakin, a quintessential desmosomal protein for cellular adhesion, particularly within cardiac tissues. DSP gene variants can cause dilated cardiomyopathy, non-dilated left ventricular cardiomyopathy (NDLVC) and arrhythmogenic righ ventricular cardiomyopathy (ARVC), cardiac conditions known to trigger malignant ventricular arrhythmias and cause sudden cardiac death in young individuals. Nevertheless, the electrocardiographic (ECG) patterns in children carrying DSP variants are underexplored.
Methods: A retrospective analysis was conducted involving paediatric DSP gene variant carriers (
