Pharmacogenetics is opening a new era of precision medicine in psychiatry. Drug-metabolizing enzymes are characterized by genetic polymorphisms, which render a large portion of variability in individual drug metabolism. Dose adjustment based on pharmacogenetics knowledge is a first step to translate pharmacogenetics into clinical practice. However, diverse factors including cost-effectiveness should be addressed to provide clinical recommendation. To address current challenges in pharmacogenetics testing in psychiatry, this review provides an update regarding genotyping (SNP analysis, array, and next-generation sequencing), genotype-phenotype correlations, and cost-effectiveness. The current updates on pharmacogenetics in psychiatry will provide guidance for both clinician and researchers to have a consensus in harmonizing efforts to advance the pharmacogenetics field in a part of precision medicine in psychiatry.
