[PMID 19416921] Genome-wide association and meta-analysis of bipolar disorder in individuals of European ancestry. Published 2009. Found that "The most strongly associated nonsynonymous SNP rs1042779 (OR = 1.19, P = 1.8 × 10−7) is in the ITIH1 gene on chromosome 3, with other strongly associated nonsynonymous SNPs in GNL3, NEK4, and ITIH3." In particular, "Four additional nonsynonymous SNPs in this region had P < 10−5: rs2289247 (Val367Met) and rs11177 Arg27Gln in GNL3 (guanine nucleotide binding like-3), rs1029871 (Pro225Ala) in NEK4, and rs3617 (Gln315Lys) in ITIH3."
