A similarly cohesive pattern was observed within the anxiety domain, with GAD1 (feeling nervous, anxious, or on edge) and GAD2 (not being able to stop or control worrying) (r = 0.423), as well as GAD5 (being so restless that it is hard to sit still) and GAD6 (becoming easily annoyed or irritable) (r = 0.380), emerging as the most strongly connected pairs. This evidence concerns the gene GAD2 and Anxiety.
