No association between the oligodendrocyte-related gene PLP1 and schizophrenia in the Japanese population

Abstract

PLP1 is one of the major myelin-related genes. A large body of expression-based studies showed significantly lower levels of the PLP1 messenger ribonucleic acid (mRNA) transcripts in schizophrenia. Moreover, one family-based study identified a weak association signal in a male subset using 487 Chinese family trios. We carried out a population-based association study between PLP1 and schizophrenia in 1,640 subjects. Our data does not support genetic variation in close vicinity or within PLP1 locus as a susceptibility factor. © 2008 The Japan Society of Human Genetics and Springer.
