In addition, a number of sex-specific genetic associations with schizophrenia risk have been reported for several genes such as ZNF804A (Zhang et al. 2011), the myelin transcription factor 1-like (MYT1L) (Li et al. 2012), and interferon γ (IFN-γ) (Paul-Samojedny et al. 2011). Here, IFNG is linked to schizophrenia.
