CIDR-Whole Genome Sequencing: Prospective Birth Cohort to Elucidate Etiology of ADHD in US Minority Children
Attention Deficit Hyperactivity Disorder (ADHD) is the most common pediatric developmental disability, affecting at least 6 million U.S. children; children from minority racial and ethnic populations, such as Black children, are at even higher risk. A major challenge in preventing and treating ADHD is that the causes remain unclear. Available data suggest that both genetic and early life environmental factors may play a role. On the genetics forefront, although an increasing number of genome-wide association studies (GWAS) have been conducted, and many genetic variants have been linked to risk of ADHD, these loci only explain a small fraction of ADHD. One puzzle has been the substantial discrepancy in estimated heritability of ADHD by GWAS (10% to 28%) vs. family-based studies (~80%).... (for more see dbGaP study page.)
