Zinc finger protein 804A is a protein that in humans is encoded by the ZNF804A gene.[5] The human gene maps to chromosome 2 q32.1 and consists of 4 exons that code for a protein of 1210 amino acids (137 kDa).[6]
Little is known about the characteristics and function of the encoded protein. However, the protein sequence codes for a domain characteristic of a classical C2H2-type

Association with schizophrenia
In humans, ZNF804A is expressed broadly throughout the brain, especially in the developing hippocampus and the cortex, as well as in the adult cerebellum.[10] ZNF804A is expected to bind DNA and thus regulate gene expression like other zinc finger proteins.[6] The mouse homologue of ZNF804A, zfp804a, has recently been reported as a target for HOXC8, suggesting that ZNF804A may be involved in the regulation of early neurodevelopment.[7]
A Genome-wide association study (GWAS) has identified ZNF804A as a susceptibility gene for schizophrenia.[11] From family, twin, and adoption studies, schizophrenia is found to have heritability of ~80%[7] and it is suspected that risk results from multiple genetic variants of small effect. The single-nucleotide polymorphism (SNP) rs1344706 in intron 2 of ZNF804A has been identified as a variant that is most strongly associated with schizophrenia.[11]
The same SNP has been reported to correlate with slightly disturbed functional coupling of several brain regions in healthy persons, resembling the changes described in schizophrenia.[12][13][14] A further study revealed that the SNP rs1344706 was consistent with schizophrenia association in European patients, but not in Han Chinese patients. Moreover, the study showed that SNPs rs1021042 and rs359895 are associated with schizophrenia in Han Chinese patients, and that the rs359895 allele increases the promoter activity of ZNF804A.[7] The results of another study suggest that there is no relationship between variant rs1344706 and impaired cognitive function in schizophrenia patients[6] and the results of yet another study indicate that ZNF804A also plays a role in how schizophrenia symptoms respond to antipsychotics.[15]
