ARTN and attention deficit-hyperactivity disorder: Similarly, conditioning on the expression of ELOVL1, CCDC24, and ARTN depending on the panel demonstrates expression-driven signals in a previously implicated ADHD loci (rs11420276 lead SNPGWAS = 1.1E−12, when conditioned on ELOVL1, CCDC24, and ARTN lead SNPGWAS = 7.1E−04) explaining 0.774 of the variance (Fig. 2d).
