The single nucleotide polymorphism rs1344706 in ZNF804A gene is closely related to functional abnormalities of the human brain. However, these results are inconsistent. This association was verified by meta-analysis in this study.Methods: Fifteen studies on functional magnetic resonance imaging involving 1710 healthy individuals were included in the systematic review and meta-analysis used by Anisotropic Effect-Size Signed Differential Mapping software.Results: Functional connectivity of the right dorsolateral prefrontal cortex (rDLPFC)–left hippocampus in the rs1344706 risk allele carrier was significantly increased (z = 2.066, p < 0.001), while those in the rDLPFC–left middle frontal gyrus (z = − 1.420, p < 0.001) and rDLPFC–right middle frontal gyrus (z = − 1.298, p < 0.001) were significantly decreased. Neural activity of the left anterior cingulate gyrus in the rs1344706 risk allele carrier was significantly decreased (z = − 2.525, p < 0.001). Sensitivity analysis was almost stable, and no publication bias was found.Conclusion: The changes in brain function have a clear correlation with ZNF804A gene in healthy individuals, which indicate the contribution of genetic variants on brain dysfunction.Registration Number: This meta-analysis is registered in PROSPERO (No. CRD42016051331).Keywords: functional magnetic resonance imaging, zinc finger protein 804A, meta-analysis
