DNA methyltransferase-dependent DNA methylation in developing interneurons seems to be implicated in schizophrenia, as prenatal stress in mice elevates Dnmt1 and Dnmt3a expression in GABAergic interneurons and induces behaviors indicative of a schizophrenia-like phenotype in their offspring (Matrisciano et al., 2013). The gene discussed is DNMT1; the disease is schizophrenia.
