Result Summary |
The results indicated that although the rs2267735 'cc' genotype was not associated with total PTSD symptoms, it could significantly predict severity of PTSD's emotional numbing symptoms in women. The findings suggest that the PACAP-PAC1 receptor pathway may play an important role in female human responses to tramatic stress. |

Only emotional numbing symptoms were associated with rs2267735 in women, but not men. The rs2267735 'CC' genotpe also was associated with only emotional numbing symptoms in women after controlling for demographic variables.
