EGR4 and schizophrenia: Although EGR3 itself is not located at one of the 145 loci associated with risk for schizophrenia, each of the other members of the EGR family, EGR1, EGR2, EGR4, as well as the EGR co-regulatory binding factor NAB2 each, map to schizophrenia GWAS loci [19–21], and EGR3 interacts in a co-regulatory feedback loop with EGR1, EGR2, and NAB2 [18].
