In KEGG analysis, several cardiomyopathy-related pathways, such as dilated cardiomyopathy, metabolic pathways, calcium signaling pathway, adrenergic signaling in cardiomyocytes, arrhythmogenic right ventricular cardiomyopathy, and hypertrophic cardiomyopathy were detected, indicating that MAP4 phosphorylation may correlate with these diseases. Here, MAP4 is linked to arrhythmogenic right ventricular cardiomyopathy.
