Consistent with these findings, prior studies focusing on layers 2-superficial 3 found greater deficits in transcripts for both enzymes of GABA synthesis, GAD65 and GAD67, and for SST mRNA, in SZ than in BD or MD (Dienel et al., 2023a; Dowling, Dienel, Barile, Bazmi, & Lewis, 2023). The gene discussed is GAD2; the disease is Behcet disease.
