We investigated whether genetic variation in two neuropeptides implicated in the stress response, neuropeptide Y (NPY) and pituitary adenylate cyclase-activating polypeptide receptor 1, interacted with childhood trauma (CT) to influence AS. DESIGN AND METHODS: This cross-sectional study examined the CT x genetic variant effects on AS in 951 adolescents who self-identified as Xhosa or South African Colored (SAC) ethnicity.

RESULTS: In Xhosa females, the NPY rs5573 A allele and rs3037354 deletion variant were associated with increased (p = 0.035) and decreased (p = 0.034) AS, respectively. The interaction of CT and the NPY rs5574 A allele increased AS in SAC female participants (p = 0.043). The rs3037354 deletion variant protected against AS with increased CT in SAC male participants (p = 0.011).

CONCLUSIONS: The NPY rs5574 A allele and rs3037354 deletion variant interact with CT to act as risk and protective factors, respectively, for AS in an ethnicity- and sex- differentiated manner. Our results reaffirm the role of NPY and gene-environment interactions in anxiety-related behaviors and reinforce the need for psychiatric genetics studies in diverse populations.
