Genetic factors determining the response to antipsychotic treatment in schizophrenia are poorly understood. A new schizophrenia susceptibility gene, the zinc-finger gene ZNF804A, has recently been identified. To assess the pharmacogenetic importance of this gene, we treated 144 schizophrenia patients and assessed the response of positive and negative symptoms by PANSS. Patients homozygous for the ZNF804A risk allele for schizophrenia (rs1344706 AA) showed poorer improvement of positive symptoms (7.35 ± 0.46) compared to patients with a protective allele (9.41 ± 0.71, P = 0.022). This provides further evidence that ZNF804A is of functional relevance to schizophrenia and indicates that ZNF804A may be a novel target for pharmacological interventions.
