Pharmacogenetics (PGx) is the study and application of how interindividual differences in our genomes can influence drug responses. By evaluating individuals' genetic variability in genes related to drug metabolism, PGx testing has the capabilities to individualise primary care and build a safer drug prescription model than the current "one-size-fits-all" approach. In particular, the use of PGx testing in psychiatry has shown promising evidence in improving drug efficacy as well as reducing toxicity and adverse drug reactions. Despite randomised controlled trials demonstrating an evidence base for its use, there are still numerous barriers impeding its implementation. This review paper will discuss the management of mental health conditions with PGx-guided treatment with a strong focus on youth mental illness. PGx testing in clinical practice, the concerns for its implementation in youth psychiatry, and some of the barriers inhibiting its integration in clinical healthcare will also be discussed. Overall, this paper provides a comprehensive review of the current state of knowledge and application for PGx in psychiatry and summarises the capabilities of genetic information to personalising medicine for the treatment of mental ill-health in youth.

Background: The effective implementation of personalized pharmacogenomics (PGx) requires the integration of released clinical guidelines into decision support systems to facilitate clinical applications. Large language models (LLMs) can be valuable tools for automating information extraction and updates.
Objective: This study aimed to assess the effectiveness of repeated cross-comparisons and an agreement-threshold strategy in 2 advanced LLMs as supportive tools for updating information.

Purpose/background: Multiple meta-analyses have suggested that pharmacogenomic (PGx) testing may be a valuable tool to improve clinical outcomes for patients with major depressive disorder (MDD) who have failed at least one treatment. However, these meta-analyses included studies with different PGx tests and different trial designs, which produce uncertainty when interpreting results. To investigate the clinical utility of a single weighted multigene PGx test, a meta-analysis was performed for prospective studies utilizing this PGx test in adult patients with MDD.

Medication discontinuation attributable to adverse drug reactions (ADRs) and/or inefficacy remains a concern of psychotropic medications among children and adolescents. Pharmacogenetic (PGx) testing has been proposed to individualize treatment, although its utility remains uncertain. We retrospectively evaluated whether PGx testing of two key metabolism genes (i.

Objectives: Many patients with major depressive disorder must try multiple antidepressants before they identify a drug that is both effective and tolerable. Pharmacogenomic (PGx) testing may provide clinicians with guidance around medication choice based on a patient's drug response-related genetic variants. However, this technology is not routinely used in clinical care in Canada, and the views of key actors in the implementation process are largely unknown.

Background: CYP2D6 affects metabolism of several opioids; however, the clinical impact of genetic variants on efficacy has limited evidence in large patient populations.
Objective: This study aims to assess the impact of CYP2D6 phenotype on pain response in an elective pharmacogenomic (PGx) screening population prescribed opioids.
Methods: A retrospective review was conducted on hospitalized patients with CYP2D6 genotyping, prescribed either codeine, tramadol, hydrocodone, or oxycodone within 24 months prior to PGx testing and through 36 months after results.
