Among these 60 probes, three probes (cg03700121, cg18430990, and cg19670431) in the coiled-coil domain containing 86 (CCDC86), transmembrane protein 240 (TMEM240), and sortilin-related Vps10p domain containing receptor 2 (SorCS2) genes were significantly associated with ADHD (FDRs < 0.05, Table 4). Here, CCDC86 is linked to attention deficit-hyperactivity disorder.
