Prior work has shown reduced serotonin transmission to be associated with impulsivity and behavioral problems. The current study assessed the association between ADHD and two variants of the serotonin transporter gene: the 44-bp deletion/insertion polymorphism (5-HTTLPR) and the 17 bp-repeat polymorphism in intron 2 (STin2.VNTR). We hypothesized that ADHD phenotypes associated with impulsivity would show an association with these variants. Two-hundred and ninety-three ADHD trios were genotyped and analyzed using transmission disequilibrium test (TDT) analysis and haplotype analysis. We found no association between the STin2.VNTR and ADHD, but did find preferential transmission of the S allele of the 5-HTTLPR polymorphism (chi(2) = 5.751, P = 0.016) to probands with ADHD. Haplotype analysis found the L/10 haplotype was over-transmitted (chi(2) = 6.172, P = 0.013), while L/12 was under-transmitted to probands with ADHD (chi(2) = 4.866, P = 0.027).
