Independent of comorbidity with depression, anxiety disorders were significantly (p ≤ 6.409E–08) associated with altered DNA methylation at 148 CpGs partly mapping to genes previously implicated in processes related to anxiety, brain disorders, learning or plasticity (e.g., GABBR2, GABRD, GAST, IL12RB2, LINC00293, LOC101928626, MFGE8, NOTCH4, PTPRN2, RIMBP2, SPTBN1) or in a recent cross-anxiety disorders EWAS (TAOK1) after pre-processing and quality control (N = 378 vs. N = 295). Here, SPTBN1 is linked to depressive disorder.
