This article focuses on the first generation of pharmacogenetic tests that are potentially useful in psychiatry. All pharmacogenetic tests currently on the market, or soon to be marketed in psychiatry, for which some information has been published in peer-reviewed journal articles (or abstracts), were selected. Five pharmacogenetic tests are reviewed in detail: the Roche AmpliChip CYP450 Test, the Luminex Tag-It Mutation Detection Kit, the LGC clozapine response test, the PGxPredict: Clozapine test, and the Genomas PhyzioType system. After reviewing these tests, three practical aspects of implementing pharmacogenetic testing in psychiatric clinical practice are briefly reviewed: (1) the evaluation of these tests in clinical practice, (2) cost-effectiveness, and (3) regulatory oversight. Finally, the future of these and other pharmacogenetic tests in psychiatry is discussed.

Pharmacogenetic Testing for Predicting Methylphenidate Treatment Outcomes in Childhood Attention Deficit Hyperactivity Disorder in Turkey: Focus on Carboxylesterase 1, Latrophilin-3, and Catechol-O-Methyltransferase.

Pharmacogenetic studies involving Carboxylesterase 1 (CES1), Latrophilin-3 (LPHN3), and Catechol-O-methyltransferase (COMT) revealed individual differences regarding therapeutic response in children with attention deficit hyperactivity disorder (ADHD) under methylphenidate (MPH) treatment. This study aimed to evaluate MPH's association with the adverse effect status in children and its relationship with CES1, LPHN3, and COMT in the Turkish population. The study included 102 children and adolescents with ADHD, who were categorized as responders, or the adverse effect group based on their treatment response.

This article examines the frequency distribution of Tier 1 pharmacogenetic variants of the Association for Molecular Pathology Pharmacogenomics Working Group Recommendations in two large (>1.000 individuals) cohorts of the admixed Brazilian population, and in patients from the Brazilian Public Health System enrolled in pharmacogenetic trials. Three Tier 1 variants, all in DPYD, were consistently absent, which may justify their non-inclusion in genotyping panels for Brazilians; 13 variants had frequency < 1.

Pharmacogenetics is a branch of genomic medicine aiming to personalize drug prescription guidelines based on individual genetic information. This concept might lead to a reduction in adverse drug reactions, which place a heavy burden on individual patients' health and the economy of the healthcare system. The aim of this study was to present insights gained from the pharmacogenetics-based clustering of over 500 patients from the Croatian population.

Fentanyl is a synthetic opioid widely used for its potent analgesic effects in chronic pain management and intraoperative anesthesia. However, its high potency, low cost, and accessibility have also made it a significant drug of abuse, contributing to the global opioid epidemic. This review aims to provide an in-depth analysis of fentanyl's medical applications, pharmacokinetics, metabolism, and pharmacogenetics while examining its adverse effects and forensic implications.

Background/objectives: Pharmacogenetics (PGx) aims to identify individuals more likely to suffer from adverse reactions or therapeutic failure in drug treatments. However, despite most of the evidence in this area being from European populations, some diseases have also been neglected, such as HIV infection, malaria, and tuberculosis. With this review, we aim to emphasize which pharmacogenetic tests are ready to be implemented in treating neglected diseases that have some evidence and call attention to what is missing for these three diseases.
