Genetics

This blog post examines a population-based study investigating how polygenic risk scores influence the lifetime risk of developing multiple sclerosis. Using data from a Dutch birth-year cohort, the article shows that individuals with the highest genetic risk have a substantially greater probability of developing MS than those with low genetic risk, with notable sex-specific differences in absolute risk. The post also discusses the clinical relevance of these findings, including the potential use of polygenic risk scores to support diagnostic confidence while emphasizing that genetic risk should complement, not replace, established neurological assessment.
