Epstein-Barr virus variant linked to MS risk in study
Key Takeaway
A version of an Epstein-Barr virus gene was linked to MS risk, and virus-related genes showed changes in MS blood and brain samples.
What They Found
Genes that work with the Epstein-Barr virus (a virus linked to MS) appeared more often in parts of human DNA tied to MS risk. The researchers did not find the same pattern for the other diseases they examined. In blood and brain samples from people with MS, some of these genes showed changes in how active they were. The researchers also found a virus gene active in MS brain tissue. One version of that virus gene was linked to MS risk and lowered the activity of a human gene tied to MS risk.
Who Should Care and Why
The study examined genetic data and blood and brain samples from people with MS. It focused on how human genes and genes from the Epstein-Barr virus (a virus linked to MS) relate to MS risk. The researchers compared the genetic pattern they found with patterns tied to other diseases. They found a pattern that appeared specific to MS among the diseases examined. The findings help describe a possible link between the virus and MS, but do not prove how MS begins.
Important Considerations
You cannot tell from this study whether a version of the virus gene will predict your MS risk. The abstract does not give the number of people studied. It also does not show that changing these genes would prevent or treat MS.

Whether you’ve recently been diagnosed with Multiple Sclerosis (MS) or are seeking to broaden your understanding of this complex, neurodegenerative disease, navigating the latest research can feel overwhelming. Studies published in respected medical journals like Proceedings of the National Academy of Sciences of the United States of America often range from early-stage, exploratory work to advanced clinical trials. These evidence-based findings help shape new disease-modifying therapies, guide symptom management techniques, and deepen our knowledge of MS progression.
However, not all research is created equal. Some clinical research studies may have smaller sample sizes, evolving methodologies, or limitations that warrant careful interpretation. For a more comprehensive, accurate understanding, we recommend reviewing the original source material—accessible via the More Details section above—and consulting with healthcare professionals who specialize in MS care.
By presenting a wide range of MS-focused studies—spanning cutting-edge treatments, emerging therapies, and established best practices—we aim to empower patients, caregivers, and clinicians to stay informed and make well-informed decisions when managing Multiple Sclerosis.
