Genetics

This blog post examines evidence that lipid metabolism and inherited genetic variation may jointly influence disability progression in multiple sclerosis. Drawing on a five-year longitudinal cohort study, it explains how a cumulative score based on lipid-related genetic polymorphisms was associated with faster annualised EDSS progression and modified the effects of HDL cholesterol and the total cholesterol-to-HDL ratio. The article also evaluates the study’s biological implications, methodological limitations and potential relevance to biomarker development, patient stratification and future precision-medicine approaches in multiple sclerosis.
