NOTCH1 and Anxiety: These clusters particularly involved genes related to regulatory subunits of cAMP-dependent protein kinases, such as PRKAR2A, cAMP-responsive element-binding pathway, circadian rhythms, such as CLOCK, ARNT1, CRY2, PER1, and PER2, and anxiety and depression, such as NOTCH1, NOTCH2 and ANK2.
