Interesting to note were the differentially expressed genes in mix-TH-VGLUT3 neurons in schizophrenia (in total 10; Fig. 3G), including increased expression of glypican 6 (GPC6) in schizophrenia compared to controls (Supplementary Fig. 7C and Supplementary Table 14). This evidence concerns the gene SLC17A8 and schizophrenia.
