Genetics

This blog post examines a recent scientific study investigating the genetic determinants of multiple sclerosis susceptibility in people of South Asian and African ancestry living in the United Kingdom. It highlights how most multiple sclerosis genetics research has historically focused on European ancestry populations, limiting the accuracy of genetic risk prediction across diverse groups. The article discusses the study’s genome-wide association analyses, HLA findings, polygenic risk score results, and broader implications for equitable genomic medicine, emphasizing the need for larger multi-ancestry studies to improve biological discovery, fine-mapping of causal variants, and future therapeutic development.
