The purpose

The ultimate goal of this study is to find specific polymorphism of candidate genes (particularly of dopaminergic and noradrenergic systems) associated with intermediate phenotypes (e.g., executive functions, IQ, and other neuropsychological function) and/or phenomenological phenotypes (subtypes, comorbidity, dimensional approach) of ADHD. We propose to replicate the analysis of the candidate genes identified by previous genetic studies and recent findings from GWAS on ADHD using the candidate gene association study design (family-based case control study using parental controls and population-based case-control study). These results may lead our research team: (1) to resolve controversies over inconsistent findings in previous genetic studies and contribute to the literature on the validity of ADHD and its subtypes using clinical and genetic data; (2) to identify potential endophenotypes for ADHD genetic studies; and (3) to identify specific polymorphism of candidate genes and gene expressions of dopaminergic and noradrenergic systems associated with executive functions measured by the CANTAB.
