In addition, in a previous thalamic transcriptome study72 using the samples from SMRI neuropathology collection (n=15 each, schizophrenia/BPD/MDD/controls), PCDH17 expression was again increased in patients with BPD versus healthy controls (P-value=0.047, Supplementary Figure 3). Here, PCDH17 is linked to major depressive disorder.
