The co-detection of eight genes involved in neuronal myelination was also consistent with previous analysis of cortical gene expression in schizophrenia, which reported dysregulation of MAG, MBP, MOBP, PLP1, PLLP, and CNP; transcription factor OLIG1; and oligodendroctye development and myelination associated gene CLDN11 [4], [9], [19], [36], [55]. This evidence concerns the gene PLLP and schizophrenia.
