When we enlarged the parameters of set‐based analysis (set −sex‐max 50, −set‐r2 .3 and −set‐p .1) to include more SNPs, the set‐based analysis for the pathway DLGAP1‐DLG4‐NMDA also showed significance in ADHD symptom score (p = .0313). The gene discussed is DLGAP1; the disease is attention deficit-hyperactivity disorder.
