Our data support findings from two meta-analyses of GWA-studies searching for common risk variants in ANK3 for schizophrenia, bipolar disorder or unipolar depression: One study combining Meta-analysis and additional genotyping of a bipolar and unipolar sample from the US, the UK, Ireland, and Netherlands, found no association of variants in ANK3 and unipolar depression. This evidence concerns the gene ANK3 and bipolar disorder.
