Schizophrenia has been associated with several single nucleotide polymorphisms or haplotypes of DTNBP1 [3,6,9] and analyses based on gene-wide association studies, coupled with other genetic and gene expression studies in humans and animals, highlighted DTNBP1 as a susceptibility gene for schizophrenia [3]. This evidence concerns the gene DTNBP1 and schizophrenia.
