Examples include genes from the IGF2-H19 imprinted locus on chromosome 11p15, e.g., IGF2, H19, and miR483, and DLK1, DIO3, and miR134, which reside within the DLK1-DIO3 imprinted locus at 14q32 and whose misregulation is linked to schizophrenia and bipolar disorder56,57. This evidence concerns the gene DIO3 and schizophrenia.
