The diagnosis followed DSM-IV criteria, and personality dimensions were evaluated with the Temperament and Character Inventory (TCI). There were no significant differences in allele and genotype frequencies between cases and controls. Patients carrying the G allele of rs1800544 presented lower scores in harm avoidance, and carriers of the T allele of rs553668 had more novelty seeking and less harm avoidance and persistence. Additionally, the haplotype carrying the G-G-T alleles (rs1800544–rs1800545–rs553668) was associated with lower scores in harm avoidance and persistence, and higher scores in novelty seeking compared to other haplotypes. These findings suggest that the conflicting findings obtained in association studies between ADRA2A polymorphisms and ADHD might be related to temperament profiles, and support additional studies addressing these effects in larger samples.]]> Wed 07 Apr 2021 13:46:40 AEST ]]>
