PLCL1 and attention deficit-hyperactivity disorder: While we did not find significant enrichment for GWAS signals in our DEGs (SCZ—p = 0.349, BD + SCZ—p = 0.427, ASD—p = 0.435, MDD—p = 0.572, PTSD—p = 0.572, suicide attempt in SCZ—p = 0.739, OCD—p = 0.74, BD—p = 0.954, ADHD—p = 0.966), we found overlap of five DEGs (CACNA1C, C4A, GRAMD1B, PLCL1, and ZNF804A) with genes annotated to genome-wide significant SNPs in SCZ [1].
