Association study of 21 circadian genes with bipolar I disorder, schizoaffective disorder, and schizophrenia

Abstract

Several suggestive, novel associations were detected with circadian genes and BPI and SZ/SZA, but the present analyses do not support associations with common polymorphisms that confer risk with odds ratios greater than 1.5. Additional analyses using adequately powered samples are warranted to further evaluate these results.
