This consideration could be supported by data in LiverTox database which provides likelihood scores of individual drugs for drug-induced liver toxicity based on clinical reports and FDA documents, showing the different risk among ACE inhibitors (e.g., E* [unproven but suspected]: perindopril, quinapril, trandolapril; D [possible]: benazepril; B [highly likely]: captopril, enalapril, lisinopril) [26]. The gene discussed is ACE; the disease is toxicity.
