The present SCZ-BD associated SNPs implicated three promising candidate genes for shared BD-SCZ etiology, i.e., CACNB2, GRM3, and GRIN2A. The gene CACNB2 encodes an L-type voltage-gated calcium channel subunit, and is a reported genome-wide significant risk gene for several psychiatric disorders, including SCZ and BD [17]. This evidence concerns the gene GRIN2A and psychiatric disorder.
