On the other hand, antipsychotic‐treated schizophrenia patients had significantly lower peripheral IGF‐1 levels compared to healthy controls, but these results were not robust in the sensitivity analysis which may potentially be related to differences in dosage, duration of treatment, or receptor‐binding profiles of different antipsychotics (Siafis et al., 2018; Wu et al., 2008). The gene discussed is IGF1; the disease is schizophrenia.
