Result Summary |
A gene x intervention x time effect was detected for individual polymorphisms, in particular the PACAP receptor, ADCYAP1R1. Subjects who did not receive treatment had higher symptoms than those who received intervention. Furthermore, subjects with the "risk" genotypes who did not receive intervention had higher PTSD symptoms compared to those with the "low risk" or "resilience" genotypes or those who received intervention. |

Subjects with the risk genotype (CC) were more likely to be diagnosed with PTSD at week 12 (87.5%) compared to carriers of the low-risk allele (12.5%) if they were assessed-only, whereas there was no difference between genotype risk groups in the intervention cohort.
