Note. DRD3 = dopamine receptor D₃; PTSD = posttraumatic stress disorder; SNP = single nucleotide polymorphism; D = discovery sample; R = replication sample; bp = base pair; freq = frequency; aff = affected; unaff = unaffected; OR = odds ratio. SNPs that were significant after permutation testing are highlighted in bold font.
