A reduced expression of Egr3 is reported in the brains of schizophrenics (Mexal et al., 2005; Yamada et al., 2007) and an allelic variant of the Egr3 locus confers increased likelihood of schizophrenia (albeit in an ethnicity-dependent-manner) (Huentelman et al., 2015). Here, EGR3 is linked to schizophrenia.
