Recently, Kendler and colleagues (2007) replicated a high genetic correlation between major depression (MD) and generalized anxiety disorder (GAD) (1.0 in females, 0.74 in males). Interestingly, they also examined the role of neuroticism (N) and found that the genetic factors indexed by N contributed around 30 % to the genetic correlation between MD and GAD, substantially less than the authors had expected. Hence, they considered their results as 'somewhat disappointing'.
