Moreover, six GO items and six KEGG pathways were enriched in combinations of those four genes (P < 0.05; Figure 7B–7E), including in the regulation of voltage-gated ion transport and ion transmembrane transport function, action channel activity function, adrenergic signaling pathway, oxytocin signaling pathway, and hypertrophic cardiomyopathy. This evidence concerns the gene OXT and hypertrophic cardiomyopathy.
