Figure 3. Abnormal Involuntary Movements Scale (AIMS) scores according to 5-HT2C (HTR2C) receptor (upper panel) and 5-HT2A (HTR2A) receptor (lower panel) genotype. Scores in younger patients (<47 years) are shown on the left of each panel and in older patients (>47 years) on the right of each panel. For HTR2C: Old cys-cys versus Old cys-ser, P=0.02; versus Old serser, P=0.001. For HTR2A: Old 102-TT versus Old 102-TC, P=0.01; versus Old 102-CC, P=0.01. No differences were significant in the young groups. Reproduced from reference 13: Segman RH, Lerer B.
