For example, several GWAS and other genetic studies have found both rare and common variants in ANK3, which encodes ankyrin-G (AnkG), associated with bipolar disorder (Baum et al., 2008; Ferreira et al., 2008) and schizophrenia (Cruz et al., 2009; Schizophrenia Psychiatric Genome-Wide Association Study (GWAS) Consortium, 2011). This evidence concerns the gene ANK3 and bipolar disorder.
