We also examined the association of rs1344706[T] with psychosis by including bipolar samples from Iceland (N= 404) and from Norway (N= 205). The strength of the evidence for association increased (P = 0.00065 from P = 0.0029, see Table 2 for psychosis analysis and Supplementary Table 2 for bipolar-only analysis), consistent with the results of the initial report.4
