As expected, the immune transcripts that contributed to the high and low immune groups (SERPINA3, TNFα, IL6, IL1β) were elevated in the schizophrenia/high immune subgroup above both the control/low and the schizophrenia/low immune subgroups (see Supplementary Fig. 4 to view magnitude of change). This evidence concerns the gene SERPINA3 and schizophrenia.
