  4. ADHD Etiology -Genetics • Up to 92% concordance in monozygotic twins • Heritability - .75 (twin studies) • Comparable to schizophrenia • Panic - .48; Height - .92 • Siblings - 26-50% in full; 9% in half • First degree family members – 20-25% • Dopamine transporter gene (DAT1), chr 5 • Dopamine receptor D4 (DRD4*7), chr 11
