Researchers report that genetic variants influencing how people process common medications are widespread. In a nearly 100,000-person sample, everyone carried at least one variant that can interact with commonly used prescriptions.
The studies are framed as evidence that genetic testing could help tailor treatment. One outlet emphasizes the broad likelihood that people have variants relevant to drug response and points to the potential value of testing. Another highlights a larger share of participants having both an actionable variant and prior exposure to a medication known to be affected by it. Together, the reports focus on improving prescribing by accounting for inherited differences, but they differ in what proportion and practical implication they stress.
