This article reviews some of the most recent findings in genetics and pharmacogenetics of schizophrenia-especially those with clinical implications.

There are limited data on clinical and biological predictors of antipsychotic drug response. The ability to identify those patients who will respond well to psychotropic drug treatment or who will be at a higher risk for adverse effects could help clinicians avoid lengthy ineffective drug trials and limit patients’ exposure to those effects. Moreover, better predictability of treatment response early in the course of a patient’s illness can result in enhanced medication adherence, a significant predictor of relapse prevention.
