DTNBP1 and schizophrenia: Not only have several genome scans reported linkage of chromosome 6p22–24 to schizophrenia [11-14], but also association has been reported between schizophrenia and a set of individual markers and haplotypes spanning the chromosomal region containing the DTNBP1 gene (6p22.3), a finding which has been replicated in several different populations [15-24].
