However, while a meta-analysis (Yao et al. 2015) failed to confirm a significant association between schizophrenia and the TaqIA polymorphism, an association with another DRD2 SNP was reaffirmed, and findings from a genome-wide association study also support the relevance of DRD2 polymorphisms in schizophrenia disorders (Schizophrenia Working Group of the Psychiatric Genomics 2014). This evidence concerns the gene DRD2 and schizophrenia.
