If you’ve tried different medications without success, or experienced side effects that stop you from feeling better, you may have wondered: “Why isn’t my treatment working for me?” Pharmacogenetic testing (PGx) can help. By looking at your DNA, it shows how your body processes medications—giving doctors clues about which drugs may work best, and which may cause problems. But one big question remains: how can I get pharmacogenetic testing on the NHS?

Methotrexate is a drug whose efficacy is affected by our genes. The MTHFR gene can influence folate metabolism and impact Methotrexate (MTX) therapeutic outcome and potential toxicity. Based on my genetic phenotype, I can reveal that I have the G/G variant of MTHFR, meaning that if I needed Methotrexate, I would have a decreased risk of toxicity.
