TSEN54 and major depressive disorder: Neither CASKIN2 (log2FC = −0.016, p = 0.999), a protein-binding protein, nor TSEN54 (log2FC = −0.024, p = 0.999), a subunit of a tRNA endonuclease complex [33,34] were differentially expressed in association with depression symptoms in the LOAD sample or the sex-stratified analysis.
