As found in the previous GWAS results (Demontis et al., 2019), as well as in the current large meta-GWAS, several genes (e.g., DUSP6, SEMA6D, ST3GAL3, FOXP1 and FOXP2, and SORCS3) linked to the Wnt pathways (canonical and non-canonical) were found to be associated with ADHD (Demontis et al., 2023). This evidence concerns the gene DUSP6 and attention deficit-hyperactivity disorder.
