While its direct involvement in the development of depression or BC is not known, this SNP interacts with several genes that have already been reported (i.e., TRAF3 and RCOR1 [53, 54]), or that could play a role in the pathogenesis of the two traits (i.e., AMN, ANKRD9, and MIR4309). This evidence concerns the gene TRAF3 and major depressive disorder.
