Current guidelines by CPIC and DPWG, though foundational, are largely based on European and East Asian data, limiting their applicability in highly admixed populations. This article presents the rationale and methodology of RELIVAF (Latin American Network for the Implementation and Validation of Pharmacogenomic Clinical Guidelines), which aims to produce region-specific recommendations aligned with local genetic profiles, healthcare systems, and regulatory landscapes. The framework integrates international standards with country- and ancestry-specific allele frequencies, effect sizes, drug availability, and implementation constraints. It also incorporates educational strategies to promote pharmacogenomic literacy among healthcare professionals. Three gene-drug pairs were prioritized for initial guideline development:\n                    <jats:italic>DPYD<\/jats:italic>\n                    -fluoropyrimidines,\n                    <jats:italic>TPMT\/NUDT15<\/jats:italic>\n                    \u2013thiopurines (paediatric ALL), and\n                    <jats:italic>CYP2C9\/VKORC1<\/jats:italic>\n                    -coumarin anticoagulants (e.g., warfarin, acenocoumarol). Selection was based on clinical relevance, allele frequency variability, and potential public health impact. By leveraging regional data and collaborative expertise, RELIVAF aims to deliver actionable, equitable, and context-specific pharmacogenomic guidance, advancing precision medicine in Latin America and serving as a model for other underrepresented regions.\n                  <\/jats:p>","DOI":"10.3389\/fphar.2026.1721828","type":"journal-article","created":{"date-parts":[[2026,1,22]],"date-time":"2026-01-22T06:53:11Z","timestamp":1769064791000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":7,"title":["Addressing genetic diversity and health inequities: RELIVAF\u2019s proposal for Latin American pharmacogenomic guidelines"],"prefix":"10.3389","volume":"17","author":[{"given":"Luis A.","family":"Qui\u00f1ones","sequence":"first","affiliation":[{"name":"Laboratory of Chemical Carcinogenesis and Pharmacogenetics (CQF), Department of Basic and Clinical Oncology, Faculty of Medicine, University of Chile","place":["Santiago, Chile"]},{"name":"Department of Pharmaceutical Sciences and Technology, Faculty of Chemical and Pharmaceutical Sciences, University of Chile","place":["Santiago, Chile"]},{"name":"Center for Cancer Prevention and Control (CECAN)","place":["Santiago, Chile"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mat\u00edas F.","family":"Mart\u00ednez","sequence":"additional","affiliation":[{"name":"Laboratory of Advanced Research in Personalized Medicine, Department of Pharmaceutical Sciences and Technology, Faculty of Chemical and Pharmaceutical Sciences, University of Chile","place":["Santiago, Chile"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rodrigo","family":"Vargas","sequence":"additional","affiliation":[{"name":"Department of Molecular Biology, Galileo University","place":["Guatemala, Guatemala"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leslie C.","family":"Cerpa","sequence":"additional","affiliation":[{"name":"Laboratory of Chemical Carcinogenesis and Pharmacogenetics (CQF), Department of Basic and Clinical Oncology, Faculty of Medicine, University of Chile","place":["Santiago, Chile"]},{"name":"Center for Cancer Prevention and Control (CECAN)","place":["Santiago, Chile"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andr\u00e9s","family":"L\u00f3pez-Cort\u00e9s","sequence":"additional","affiliation":[{"name":"Cancer Research Group (CRG), Faculty of Medicine, Universidad de Las Am\u00e9ricas","place":["Quito, Ecuador"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Farith","family":"Gonz\u00e1lez-Mart\u00ednez","sequence":"additional","affiliation":[{"name":"Toxicology and Public Health Research Laboratory, Department of Research, Faculty of Dentistry, University of Cartagena","place":["Cartagena, Colombia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dora","family":"Fonseca","sequence":"additional","affiliation":[{"name":"Universidad del Rosario.
