Objective Bipolar disorder (BD) is complex genetic disorder. Therefore, approaches using clinical phenotypes such as biological rhythm disruption could be an alternative. In this study, we explored the relationship between melatonin pathway genes with circadian and seasonal rhythms of BD.Methods We recruited clinically stable patients with BD (n=324). We measured the seasonal variation of mood and behavior (seasonality), and circadian preference, on a lifetime basis. We analyzed 34 variants in four genes (<i>MTNR1a</i>, <i>MTNR1b</i>, <i>AANAT</i>, <i>ASMT</i>) involved in the melatonin pathway.Results Four variants were nominally associated with seasonality and circadian preference. After multiple test corrections, the rs116879618 in <i>AANAT</i> remained significantly associated with seasonality (corrected p=0.0151). When analyzing additional variants of <i>AANAT</i> through imputation, the rs117849139, rs77121614 and rs28936679 (corrected p=0.0086, 0.0154, and 0.0092) also showed a significant association with seasonality.Conclusion This is the first study reporting the relationship between variants of <i>AANAT</i> and seasonality in patients with BD. Since <i>AANAT</i> controls the level of melatonin production in accordance with light and darkness, this study suggests that melatonin may be involved in the pathogenesis of BD, which frequently shows a seasonality of behaviors and symptom manifestations.
