The single nucleotide polymorphism (SNP) rs1344706 in ZNF804A (2q32.1) has been associated with schizophrenia in a genome-wide association study (GWAS). A recent candidate gene study, which replicated the positive association with rs1344706, identified another positive SNP (rs7597593) in ZNF804A associated with schizophrenia.

We performed an association study of rs7597593 in four GWAS cohorts of European ancestry. Postmortem human brain expression data of normal Caucasian individuals (n = 89) was also analyzed for examining the effect of rs7597593 on ZNF804A messenger RNA expression, using logistic regression and linear regression.

We found that rs7597593 was significantly associated with schizophrenia in the combined GWAS datasets (n = 5023, odds ratio [OR]combined = 1.15, p = .0011). Analysis of stratification by sex showed that the association was driven by the female subjects (OR = 1.29, p = .0002) and was not significant in male subjects (OR = 1.08, p = .148) in the combined sample of four cohorts. A sex by genotype interaction was near significant in both the Genetic Association Information Network sample (p = .0532) and the combined sample of four cohorts (pcombined = .0531). Gene expression analysis showed no main effects but a significant female-specific association (pfemale = .047, pmale = .335) and sex by genotype interaction (p = .0166) for rs7597593.

Our data suggest a clinical and molecular modulation by sex of the association of ZNF804A SNP rs7597593 and risk of schizophrenia.
