Though we did not observe any Bonferroni-significant (p < 5.56 × 10−4) genetic correlations between thyroid hormone metrics and psychiatric disorders, we observed suggestive positive genetic correlations between TT3 and both ADHD (p = 3.71 × 10−2) and panic disorder (p = 2.60 × 10−2) and between FT3 and panic disorder (p = 2.15 × 10−2) (Figure 2). Here, TG is linked to attention deficit-hyperactivity disorder.
