GABRA5 mRNA was significantly positively correlated with DAT mRNA (r = 0.472, p = 0.017) but not TH mRNA (r = 0.304, p = 0.140) in controls cases and was not correlated with TH or DAT mRNAs in schizophrenia cases (both: r < 0.320, p > 0.05) (Table 4). This evidence concerns the gene GABRA5 and schizophrenia.
