We found an association between ADHD and variants in eight of these genes (GALC, CERS6, SMPD1, SMPDL3B, CERS2, FADS3, ELOVL5, and CERK) in the discovery cohort, with “local replication” for associations with variants in CERS6, SMPD1, and GALC genes. The gene discussed is ELOVL5; the disease is attention deficit-hyperactivity disorder.
