PRLHR and attention deficit-hyperactivity disorder: Additionally, we uncovered PRLHR deletions in 40 ADHD cases and 12 controls (P = 5.26E − 13, OR = 8.45) as well as clinically diagnostic relevant 22q11.2 duplications and 16p11.2 duplications in 23 ADHD + ASD cases and 9 controls (P = 4.08E − 13, OR = 15.05) and 22q11.2 duplications in 34 ADHD + ASD cases and 51 controls (P = 9.21E − 9, OR = 3.93); those control samples were not with previous 22qDS diagnosis in their EHR records.
