Recent studies point to the potential role of the (pituitary) adenylate cyclase activating polypeptide receptor 1 ( ADCYAP1R1 ) gene, which has been implicated in stress response, in posttraumatic stress disorder (PTSD). Multiple genetic association studies have examined potential PTSD risk related to this gene, with mixed results. We conducted a meta‐analysis of rs2267735 in ADCYAP1R1 in PTSD. A literature search was conducted using PubMed and PsycINFO, resulting in nine studies that met criteria for inclusion in analysis. Biostat's Comprehensive Meta‐Analysis was used to conduct the main meta‐analysis on the combined sex sample, as well as two subanalyses examining effects separately in female and male participants. Results indicated that the C allele of rs2267735 conferred significant risk for PTSD in the combined sex data, OR = 1.210, 95% CI [1.007, 1.454], p = .042, and in the subsample of women and girls, OR = 1.328, 95% CI [1.026, 1.719], p = .031; but not in the subsample of men and boys, OR = 0.964, 95% CI [0.733, 1.269], p = .796. These results provide evidence for an association between ADCYAP1R1 and PTSD and indicate that there may indeed be sex differences. Implications of these findings, including the role of rs2267735 as one modulator of the stress system, are discussed.
