rs1344706 is a SNP in the ZNF804A gene, and it is probably the first SNP to have been reported as achieving genome-wide significance for psychosis. Reviews the literature, and concludes that rs1344706 is "robustly, if modestly" associated with increased risk for schizophrenia. A genome-wide association study of schizophrenia (479 cases, 2,937 controls) followed by additional testing and a meta-analysis concluded that the strongest evidence for association was around ZNF804A (rs1344706; p = 1.61 x 10e-7) and that the finding was strengthened when the affected phenotype included bipolar disorder (p = 9.96 x 10e-9).
