Only two AD datasets were available, one with the expression profiles of (dorsolateral) prefrontal cortex samples of OCD patients versus healthy controls (GSE60190 [49]) and the other with the blood expression profiles of GAD patients (GAD score 7 ≥ 5) versus normal subjects (GAD score 7 < 2) (GSE61672 [31]). Here, GAD1 is linked to generalized anxiety disorder.
