One morning, as you\u2019re getting out of bed, an intense pain grips your feet. Your toe joints are swollen again. It\u2019s been happening for months now. You decide it\u2019s time to get the problem checked out, so you pay a visit to your doctor, who tells you that you have rheumatoid arthritis.<\/p>\n
What happens next depends on who you are. If you\u2019re white, for instance, with good health insurance and access to state-of-the-art care, your doctor probably doesn\u2019t think twice before ordering a biopsy of your joint tissue and then sending the sample off for genetic testing. As luck would have it, according to the results, you\u2019re a perfect match for a powerful new therapy. It\u2019s woefully expensive, but luckily again, your insurance covers it. Within days, your pain and swelling are gone.<\/p>\n
But what if you\u2019re poor and uninsured? Even if you manage to cobble together enough money to pay for a genetic test out of pocket, there\u2019s no way you can afford the recommended treatment. Or say you\u2019re a person of color. Because researchers haven\u2019t studied many people like you, no special therapy exists that targets your disease\u2019s particular genetic profile. So your doctor prescribes the standard regimen of steroids and painkillers, which causes weight gain and puts you at risk for stomach ulcers. Plus, your feet still hurt.<\/p>\n
This future scenario is, of course, hypothetical. But it reveals both the promise and the potential pitfalls of what\u2019s known as precision medicine.<\/p>\n
