Pharmacogenomics (PGx) is the study of how your genetic makeup influences the way you respond to medications. The same drug and dose can help one person, do little for another, and cause side effects in a third, and genetics is often part of the reason.
Why response varies
Many drugs are processed by enzymes encoded by genes such as CYP2D6, CYP2C19 and CYP3A4. Depending on your variants, you may be a poor, normal or rapid metabolizer, which changes how much active drug reaches your system.
Real examples
- Clopidogrel: certain CYP2C19 variants reduce activation of this blood thinner, lowering its effect.
- Warfarin: VKORC1 and CYP2C9 variants influence the starting dose.
- Codeine: CYP2D6 status affects how much is converted to morphine.
From one-time report to living context
PGx is most useful when it is available at the moment a medication is considered, not buried in a PDF you received years ago. A longitudinal platform keeps this context current.
genyHealth.ai surfaces pharmacogenomic context from your DNA alongside your labs and wearables, and can generate physician-ready summaries so you and your doctor can make better-informed choices. Learn more.
