In order to confirm the diagnostic role of the above biomarkers in ARVC, we constructed logistic models in GSE107475, GSE107156, and GSE29819 datasets based on these four mRNAs (FBN1, COL1A1, COL5A1, BGN) and two lncRNAs (XIST, LINC00173). Here, COL5A1 is linked to arrhythmogenic right ventricular cardiomyopathy.
