Figure 6. Interactive effect of DRD3 and CYP17 genes on Abnormal Involuntary Movements Scale (AIMS) scores according to DRD3 ser9gly and CYP17 genotype. Left: patients homozygous for the DRD3 ser allele; right: carriers of the DRD3 gly allele (hétérozygotes and homozygotes). There is a significant main effect of DRD3 genotype on AIMS total score (F=14.9, df=1.106, P=0.0002) and a significant interaction between DRD3 and CYP17 genotype (F=4.2, df=2,.106, P=0.02). *P=0.03, post-hoc Newman-Keuls test.
