- Background: Several studies of the dystrobrevin-binding protein 1 gene (DTNBP1), neuregulin 1 (NRG1), D-amino-acid oxidase (DAO), DAO activator (DAOA, G72), and metabotropic glutamate receptor 3 (GRM3) genes have suggested an association between variants of these genes and schizophrenia. Methods: In a replication attempt, single-nucleotide polymorphisms of the DTNBP1, NRG1, DAO, DAOA, and GRM3 genes were analyzed in three independent Scandinavian schizophrenia case-control samples. Results: One DTNBP1 and three GRM3 single-nucleotide polymorphisms showed nominal significant associations to the disease. However, after correction for multiple testing, there were no statistically significant allele, genotype or haplotype case-control differences. Conclusions: The present Scandinavian results do not verify previous associations between the analyzed DTNBP1, NRG1, DAO, DAOA, and GRM3 gene polymorphisms and schizophrenia. Additional studies and meta-analyses are warranted to shed further light on these relationships. Copyright (C) 2009 S. Karger AG, Basel
