Genetics

This blog post examines how the genetic study of multiple sclerosis has been shaped by an overreliance on European-ancestry populations and why this limits both scientific understanding and clinical translation. Drawing on the article “Towards a global view of multiple sclerosis genetics,” it explains how multi-ancestry research can improve fine mapping of causal variants, clarify the role of HLA and MHC variation, strengthen polygenic risk prediction, and reveal population-specific genetic signals. The post also highlights the ethical imperative to include under-represented communities in MS genomics so that future advances in precision medicine benefit patients across all ancestral backgrounds.
