A moderately strong, significant, positive correlation was found between an astrocyte maker (GFAP) and KAT I mRNAs in both healthy controls (ρ = 0.57, n = 33, p = 0.001, FDR p = 0.004, see Fig. 3a) and in patients with schizophrenia (ρ = 0.45, n = 36, p < 0.01, FDR p = 0.02, see Fig. 3b). The gene discussed is GFAP; the disease is schizophrenia.
