INTRODUCTION.
Attention-deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by symptoms of inattention, hyperactivity, impulsivity and emotional dysregulation that are excessive and pervasive, impairing in multiple contexts, and developmentally inappropriate. ADHD symptoms arise from executive dysfunction.
There is evidence that multiple genes contribute to the phenotype of attention deficit-hyperactivity disorder (ADHD) including ADHD4 on cytogenetic location 5p13 and genomic coordinates 5:28,900,001-42,500,000. The screenshot of the ADHD4 gene 13,600,000 bp (base pairs) of DNA sequence length is shown BELOW. Nine (9) other genes besides ADHD4 in the 5p13 cytogenetic location are listed BENEATH.
