Taking into account the genes associated at gene level with a given disorder, we found that the expression of CTNNB1 significantly correlates with ADHD in the amygdala (P = 8.9E-04, Z = −3.3246), ATF6B with SCZ in the spinal cord (P = 1.6E-06, Z = 4.7925) and DNM1 and ITPR3 with the phenotype in the CD-MA in the cortex and caudate, respectively (P = 2.6E-04, Z = 3.6516 and P = 1.8E-05, Z = −4.2860) (Table 1 and Supplementary Tables S4, –S16). This evidence concerns the gene CTNNB1 and attention deficit-hyperactivity disorder.
