Finally, the study looking at BN/BSD, BPD, and BDNF methylation in women found that women with BN/BSD and childhood physical abuse displayed greater methylation than HC across CpG sites on chromosome 11: 27,722,840–27,723,980 (p values ranging from 0.001 to 0.017, and main effect p = 0.03) [33]. This evidence concerns the gene BDNF and Borderline personality disorder.
