Among these, we highlight the presence of MAN1A1 (Mannosidase Alpha Class 1A Member 1), SDK1 (Sidekick Cell Adhesion Molecule 1) and BLM (Bloom Syndrome RecQ Like Helicase) that map in loci containing SNPs showing nominal associations with MDD in the recent GWAS2. The gene discussed is SDK1; the disease is major depressive disorder.
