Association between DRD4 −616 C/G, AS and FCD. (A) A main effect of genotype on the FCD was found in the pregenual ACC. (B) FCD analysis demonstrates a group-genotype interaction in the thalamus. (C) FCD analysis demonstrates a group-genotype interaction in the PCC. (D) Post-hoc testing demonstrated that the C-allele carriers in the PNE group had a significantly decreased FCD in the thalamus. (E) Post-hoc testing revealed that controls carrying the C allele exhibited increased FCD in the PCC. (F) The FCD of the thalamus also showed a significant negative correlation with the AS scores in C-allele carriers of the PNE group.
