GSTM2 and major depressive disorder: Additional analyses identified consistent negative correlations between BHLHE41 and activated dendritic cells (for Depression: p < 0.05; for BC: p < 0.01), EpCAM and immature B cells (for Depression: p < 0.05; for BC: p < 0.01), and GSTM2 and γδ T cells (p < 0.05) across both datasets (Figure 6C,D).
