Genetics

This research, published in Pharmacogenomics, explored whether the genes we inherit play a role in how well glatiramer acetate (GA), a common treatment for multiple sclerosis (MS), actually works. Scientists looked at the genes of almost 300 Russian patients with relapsing-remitting MS who had been on GA for at least two years and found that certain versions of genes like EOMES, CLEC16A, IL22RA2, and PVT1 were more common in people who responded well to the drug, meaning they had fewer relapses and their disability didn't get worse. Interestingly, they also discovered that specific combinations of gene versions, particularly involving EOMES and TYK2, could even be linked to a poorer response to GA. Overall, this study suggests that our genes can indeed influence how our bodies react to GA, which could eventually help doctors better predict who will benefit most from this treatment and move towards a more personalized approach to managing MS.
