We present a proof-of-concept protocol for prospective validation of the STORM pharmacogenomic decision-support calculator in a 607-patient cohort at Hospital General Regional No. 1, IMSS, Mérida, Yucatán, Mexico. The protocol defines a 30-gene panel (expanding from STORM v3.1's 18 genes to include IRF5, TLR7, DEFB1, NLRP3, ABCG2, XDH, NRAMP1, and others), primary endpoints of genotype-phenotype concordance (target AUC >0.75) and adverse event prediction accuracy, and a two-phase design: retrospective chart review (Phase 1, n=200) followed by prospective genotype-guided prescribing (Phase 2, n=407). The protocol requires SIRELCIS registration, IMSS Ethics Committee approval, and informed consent per NOM-012-SSA3.
