Recent accumulating evidence has indicated that ZNF804A (zinc finger protein 804A) may be one of the most robustly implicated genes in schizophrenia. In this report, we examined ZNF804A single nucleotide polymorphisms (SNPs) encompassing exon 4 by performing an association study that used a Han Chinese sample comprised of 492 schizophrenia patients and 516 healthy control subjects. A meta-analysis based on previous studies was also performed. For markers rs4667000 and rs1366842, significant differences in allele frequencies were found between cases and controls (Mantel-Haenszel corrected P=0.014 and P=0.025, respectively). Analysis of haplotype rs61739290-rs1366842 showed significant association with schizophrenia (global P=0.0018). Moreover, several other two-, three-, and four-SNP tests of haplotype association were also significant. A meta-analysis comprised of studies that utilized sample sets of either European and/or Han Chinese origin revealed statistically significant associations for two SNPs (rs1366842, P=0.002; and rs3731834, P=0.03) and schizophrenia. In addition, we observed a significant association between marker rsl344706 and schizophrenia (P<1.0×10-5) in combined populations. When we separately analyzed the studies by population, consistent and significant differences were found between cases and controls both in the European samples (P<1.0×10-4) and in the Chinese samples (P=0.03). In summary, we have added new evidence supporting the association between ZNF804A and schizophrenia in our Han Chinese sample. Further functional exploration of ZNF804A will greatly help us to elucidate the pathogenesis of schizophrenia and find promising new approaches for the treatment of this disorder.
