The disruption of this gene results in cortical malformations and causes serotonergic and dopaminergic cells in the midbrain to be expressed in aberrant locations. Resequencing of DNA from <jats:italic>OTX2<\/jats:italic> exons and surrounding introns from 60 individuals (15 schizophrenia, 15 bipolar disorder, 15 depression, and 15 control) revealed two intronic polymorphisms, rs2277499 (C\/T) and rs28757218 (G\/T), but no other variations. The minor allele of rs2277499 (T) did not associate with clinical diagnosis. However, using a Taqman genotyping assay, we found the rs28757218 minor allele (T) in 30 out of 720 (4.2%) individuals with bipolar disorder but only in 6 out of 526 (1.1%) control individuals (odds ratio 3.5, 95% confidence interval 1.4\u201310.4, <jats:italic>P<\/jats:italic>\u2009=\u20090.003). On the other hand, the rs28757218 minor allele was only found in 6 out of 458 (1.3%) individuals with schizophrenia. All individuals with the rs28757218 polymorphism were heterozygous for the allele. Based on this positive case\u2010control association finding, we conclude that variations in <jats:italic>OTX2<\/jats:italic> might confer risk for the development of bipolar disorder. \u00a9 2007
