Abstract
Objective: This study was intended to assess the extent to which the low-expression alleles of the serotonin transporter gene promoter
predict poor response to cognitive behavior therapy in patients with posttraumatic stress disorder (PTSD).
Method: Forty-five patients with PTSD underwent an 8-week exposure-based cognitive behavior therapy program and provided mouth
swabs or saliva samples to extract genomic DNA and classify individuals according to four allelic forms (SA, SG, LA, LG) of the 5-HTT-linked
polymorphic region (5-HTTLPR). We determined whether the 5-HTTLPR genotype predicted change in PTSD severity following treatment
(n 45) and 6 months later (n 42).
Results: After controlling for pretreatment PTSD severity and number of treatment sessions, the 5-HTTLPR low-expression genotype group
(S or LG allele carriers) displayed more severe PTSD 6 months following treatment relative to other patients.
Conclusions: This study suggests a genetic contribution to treatment outcome following cognitive behavior therapy and implicates the
serotonergic system in response to exposure-based treatments in PTSD.
