SLIT3 and major depressive disorder: Our current finding of Slit guidance ligand 3 gene, SLIT3 in antidepressant and MDD gene set is in consensus with findings from Glessner JT et al. [126], where they have performed genome-wide copy number variation scan of large cohort of MDD patients and controls and has observed 5q35.1 as the most significant locus harboring the SLIT3 gene which is integral to repulsive axon guidance.
