Hyperbilirubinemia, characterized by elevated total blood bilirubin levels including both unconjugated and conjugated forms, serves as a diagnostic marker for drug-induced liver toxicity associated with a wide range of medications. This study aimed to develop a mechanistic model for assessing hyperbilirubinemia risk using genetic markers. We developed an ordinary differential equation (ODE)-based mechanistic model of human bilirubin metabolism, incorporating key processes such as unconjugated bi
