ALK and schizophrenia: Neurons classified as ‘inh-ALK’ (P-value = 0.017), ‘inh-B’ (P-value = 0.023), and ‘remaining-mix’ (P-value = 0.035) were more abundant in schizophrenia, while those classified as ‘exc-CORIN’ (P-value = 0.017) and ‘mix-TH-VGLUT3’ (P-value = 0.05) were less abundant in schizophrenia compared to controls (n = 14 cases per group, FDR < 0.2) (Fig. 3D and Supplementary Table 12).
