Result Summary |
After adjusting for age, sex, socio-economic status, race, smoking, number of traumatic events and lifetime depression, 9R allele carriers showed almost twice the risk of PTSD compared to 10R/10R carriers. A significant (P-value=0.008) interaction was observed whereby 9R allele carriers showed an increased risk of lifetime PTSD only in conjunction with high methylation in the SLC6A3 promoter locus, controlling for the same covariates. |
