In the second part of the study reported in this paper, we examined the ZNF804A region for gain or loss of copy number, using 4235 psychosis patients, 1173 patients with other psychiatric disorders and 39 481 controls. Two psychosis patients harbored CNVs affecting at least part of ZNF804A, resulting in a P-value of 0.013 for association with psychosis. In addition, a patient with anxiety had a deletion, leading to a P-value of 0.0016 for association with psychiatric disorders.
