Conversely, EC 4.1.1.9 (malonyl-CoA decarboxylase), EC 3.1.3.37 (sedoheptulose-bisphosphatase), EC 2.2.1.10 (2-amino-3,7-dideoxy-D-threo-hept-6-ulosonate synthase), and EC 1.4.3.19 (glycine oxidase) exhibited a significant decrease in patients with early-onset psychosis compared to the non-psychotic group (Figure 6). This evidence concerns the gene MLYCD and psychotic disorder.
