AHRR and schizophrenia: Interestingly, a meta-analysis combining schizophrenia and FEP (nControls = 1387, nPsychosis = 1680) only identified 31 VMPs, including 29 that were also identified in the schizophrenia meta-analysis, and two novel VMPs affecting genes associated with neurodevelopment (TBC1D19) and dendritic spine density (AHRR) in schizophrenia [67, 68] (Figs. S12–S18, Tables S24–S29).
