New study replicates association between genetic variation and antidepressant treatment response

Pharmacogenetics, the study of genetic variation that influences an individual's response to drugs, is an important and growing focus in all of medical research, including psychiatry. It is a complex field, however, revealed by the lack of consistent and replicable findings across multiple studies, but some encouraging results are beginning to emerge. A new study scheduled for publication in the June 15th issue of Biological Psychiatry evaluated genetic markers in the treatment response of antidepressants and this work implicates the same markers as found in a prior trial.
