To further test the evidence for association, we combined the data for rs1344706 from our earlier publication(4) with data from 4 published GWAS studies, one unpublished Swedish GWAS dataset (termed SW3, from P Sullivan/C Hultman), data from additional samples we genotyped in house, and data from a ZNF804A candidate gene study from a group who had contacted us prior to genotyping their sample(10) and whose data are therefore unbiased with regard to the result.
