NEGR1 and schizophrenia: Mann–Whitney U test revealed statistically significant differences between patient and control groups only for NTM 1b and NEGR1. NTM 1b was significantly increased in schizophrenia subjects (m = 0.94) compared to controls (m = 0.64) (p < 0.001) (Figure 2D), and NEGR1 was also significantly increased in schizophrenia subjects (m = 6.07) compared to controls (m = 4.57) (p < 0.001) (Figure 2G).
