Based on a recent study, we analyzed the DNA methylation of a specific CpG site within the gene PXDN—cg10888111—in blood in the context of ELA across a set of psychiatric disorders, namely Borderline Personality Disorder (BPD), Major Depressive Disorder (MDD) and Social Anxiety Disorder (SAD), and its potential contribution to their pathogenesis. Here, PXDN is linked to psychiatric disorder.
