Objective-We tested for association of the catechol-O-methyltransferase (COMT) Val158-Met (rs4680) polymorphism with attention-deficit hyperactivity disorder (ADHD) using family-based test in Korean trios. Methods-A total of 181 subjects with ADHD along with both of their biological parents were recruited from University Hospitals in Korea. We performed a transmission disequilibrium test (TDT) on 181 trios. Results-In the TDT, we found the over-transmission of the Val allele in children with ADHD (χ2=4.21, p=0.040). Conclusion-These results suggest that the COMT Val158-Met polymorphism is associated with ADHD among the Korean population. However, this study must be replicated in larger populations.
