Several genes have shown significant association with ADHD after MAGMA analysis: ST3GAL3, KDM4A, PTPRF, SZT2, TIE1, MPL, CDC20, HYI, SLC6A9, ELOVL1, CCDC24 (chromosome 1); MANBA (chromosome 4); MEF2C 5 (chromosome 5); FOXP2 (chromosome 7); SORCS3, CUBN (chromosome 10); DUSP6 (chromosome 12); SEMA6D (chromosome 15); CDH8 (chromosome 16). This evidence concerns the gene ST3GAL3 and attention deficit-hyperactivity disorder.
