SFN and schizophrenia: When extending our analyses into larger samples of the PGC, BroadABC and iPSYCH, we found that common variants were gene-based associated with several psychiatric phenotypes in four of the seven 14-3-3 genes (SFN, YWHAB, YWHAE and YWHAZ), although only the association between YWHAE and schizophrenia survived correction for multiple testing.
