We subsequently analyzed expression of the FGF14, PVALB, GAD67 and VGAT genes and their correlations in two schizophrenia-enriched data sets and matched controls from the dorsal lateral prefrontal cortex.60, 61 Both data sets showed a significant decreased expression of FGF14, PVALB, GAD67 and VGAT (Figure 5a and Supplementary Figure 6), and a highly significant correlation between FGF14, PVALB, GAD67 and VGAT was found in all samples and in schizophrenia alone with the largest effect size in schizophrenia and controls for GAD67 (Figure 5b). Here, SLC32A1 is linked to schizophrenia.
