Of the 18 neurology panel proteins that emerged in Kuan et al. [15], seven showed significant bivariate associations with PTSD symptom severity at the 5% FDR level: BCAN, NCAN, MSR1, PVR, TNFRSF21, SKR3, and DRAXIN (|r| = 0.08–0.14; Table 1). Here, TNFRSF21 is linked to post-traumatic stress disorder.
