title: A study of a genetic association between the PTGS2/PLA2G4A locus and schizophrenia.
abstract: Six single nucleotide polymorphisms (SNPs) present in the PTGS2/PLA2G4A locus were detected among 118 British family trios of schizophrenia patients. The transmission disequilibrium test showed that SNP4 located in the 5'-flanking region of the PLA2G4A gene was associated with schizophrenia and that the haplotype analysis also showed a genetic association between the PTGS2 gene and schizophrenia. Because these two genes are arranged in a head-to-head configuration and separated by just about 149kb of DNA, they may have a combined effect on susceptibility to schizophrenia in some cases.
