MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Glutamate neurotransmission may play an important role in ADHD and other neuropsychiatric disorders. The purpose of this study is to determine the frequency of genetic mutations involving specific genes (GRM network genes) which influence glutamatergic neurotransmission. A total of 23 study sites across the USA enrolled 1,013 children, aged 6-17 years who had been previously diagnosed with ADHD. Saliva samples were submitted to The Center for Applied Genomics (CAG) at CHOP for analysis of mutations of interest. Information on medical history, including other neuropsychiatric diagnoses and family history as well as areas of academic and social concern were also collected.
Overall, the mutation frequency was 22%, with a higher prevalence of 25% observed in patients aged 6-12. When compared to mutation negative ADHD patients, the patients with the mutations of interest were more likely to have concerns about anger control and disruptive behaviors.
