The association of white matter volume in psychotic disorders with genotypic variation in NRG1, MOG and CNP: a voxel-based analysis in affected individuals and their unaffected relatives.
The A-allele of rs2070106 within the 2',3'-cyclic nucleotide 3'-phosphodiesterase (CNP), an oligodendrocyte-related gene, was reported to show reduced expression compared with the G-allele, and proposed to be associated with schizophrenia.
Expression of MAG, CNP and OLIG2 did not differ between patients with schizophrenia and controls in the grey or white matter but MOBP mRNA levels were increased in the DLPFC white matter in patients with a history of substance abuse.
