Association of tumor necrosis factor alpha gene -G308A polymorphism with schizophrenia

Journal Article


Abstract


  • Background: Tumor necrosis factor alpha (TNF��), a cytokine involved in inflammatory processes, has been implicated in the pathophysiology of schizophrenia. The chromosomal location in the major histocompatibility complex (MHC) region on 6p21.1-21.3, a region with evidence for linkage, suggests a role in susceptibility to schizophrenia. Association of the minor (A) allele of the -G308A TNF�� gene polymorphism with schizophrenia has been reported [Mol. Psychiatry 6 (2001) 79]. Methods: Association of the -G308A TNF�� gene and the lymphotoxin alpha (LT��)+A252G gene polymorphisms with schizophrenia was studied in 79 sib pair families with linkage in the MHC region and in 128 trio families using the transmission disequilibrium test (TDT). Results: Weak association of the common G allele was detected for TNF�� -G308A in both samples independently with borderline significance in the sib pair families (0.064) and with a nominally significant value of P=0.022 in the trio families. Combining both samples produced P=0.003, while LT��+A252G, located approximately 2-3 kb distally, revealed P=0.03 and the two locus haplotype yielded a P value of 0.001. Conclusion: Our data suggests association of the common G allele of the -G308A TNF�� gene polymorphism with schizophrenia in a sample of 207 families. However, linkage disequilibrium with a different allele of the TNF�� gene or another gene in the MHC region cannot be excluded. �� 2003 Elsevier Science B.V. All rights reserved.
