Discussion

Multi-cohort analysis uncovers desmocollin-2 downregulation as a biomarker for arrhythmogenic cardiomyopathy and implies diagnostic potential.

Desmocollin-2 expression is significantly reduced in arrhythmogenic cardiomyopathy myocardium compared to controls.
DSC2 downregulation correlated with age at onset of arrhythmia, indicating its potential role in clinical assessment.
Analysis utilized methods like immunofluorescence and Western Blot to demonstrate DSC2's diagnostic value.
Future research should clarify the underlying mechanisms of DSC2 downregulation in arrhythmogenic cardiomyopathy.

Ren et al. (2025) studied this question.
