Whether the effect exists in the resting state and in patients with schizophrenia remains unclear. In this study, we investigated the ZNF804 A polymorphism at rs1344706 in 92 schizophrenic patients and 99 healthy controls of Han Chinese descent, and used resting-state functional magnetic resonance imaging to explore the functional connectivity in the participants. We found a significant main effect of genotype on the resting-state functional connectivity(RSFC) between the hippocampus and the dorsolateral prefrontal cortex(DLPFC) in both schizophrenic patients and healthy controls. The homozygous ZNF804 A rs1344706 genotype(AA) conferred a high risk of schizophrenia, and also exhibited significantly decreased resting functional coupling between the left hippocampus and right DLPFC(F(2,165) = 13.43,P / 0.001). The RSFC strength was also correlated with cognitive performance and the severity of psychosis in schizophrenia. The current findings identified the neural impact of the ZNF804 A rs1344706 on hippocampalprefrontal RSFC associated with schizophrenia.展开更多

Previous studies indicated that the single nucleotide polymorphism(SNP) rs1344706 in the gene ZNF804 A encoding zinc finger protein 804 A was associated with schizophrenia in Caucasian population but not in Chinese Han population. However, current results are conflicting in Asian population. In the present study, a meta-analysis was performed to revisit the association between rs1344706 and the risk of schizophrenia in Asian, Caucasian and other populations. Electronic search of Pub Med database identified 25 case–control studies with available genotype frequencies of rs1344706 for the meta-analysis,involving a total of 15,788 cases and 22,654 controls. A pooled odds ratio(OR) with 95% confidence interval(CI) was used to assess the association. The current meta-analysis showed an association between rs1344706 and schizophrenia in Caucasian populations(P = 0.028, OR = 1.138, 95% CI:1.014–1.278; P = 0.004 for heterogeneity) and Asian populations(P = 0.008, OR = 1.092, 95%CI: 1.023–1.165; P = 0.001 for heterogeneity), but not in other populations(P = 0.286,OR = 1.209, 95% CI: 0.853–1.714, P = 0.120 for heterogeneity). Egger’s test(P 〉 0.05) and Begg’s test(P 〉 0.05) are both suggestive of the lack of publication bias for the included studies. Thus, the absence of association in other populations suggests a genetic heterogeneity in the susceptibility of schizophrenia and demonstrates the difficulties in replicating genome-wide association study findings regarding schizophrenia across different ethnic populations. To validate the association between rs1344706 and schizophrenia, further studies with larger participant populations worldwide are needed.展开更多
