When treated for depression with substrates of the protein encoded by ABCB1, carriers of one or two minor alleles at these ABCB1 SNPs have been reported to respond better than non-carriers. The antidepressant drugs that are known to be substrates include citalopram, paroxetine, amitriptyline, and venlafaxine. The relative odds of better response for rs2032583(C) carriers is 7.72 (CI: 2.8-21.3, p=0.000065) based on a study of ~400 primarily Caucasian patients.10.1016/j.neuron.2007.11.017
