Using a UK sample of ADHD subjects (aged 5-18 years), we tested the hypothesis that rs12861247 is associated with ADHD risk using a case-control approach (comparing 327 ADHD</span> cases with 358 male controls from the Wellcome Trust Case Control Consortium).
TDT analysis of the data yielded two polymorphisms that were significantly associated with ADHD (rs2770112-Transmitted: 71 Not Transmitted; 48; rs12861247-Transmitted: 43 Not Transmitted: 21), located towards the 5' end of the gene (P < 0.05).
