Genetics

This blog post examines a landmark genetic study showing that the biological drivers of multiple sclerosis progression differ from those that govern disease susceptibility. By identifying a severity-associated locus at the DYSF–ZNF638 region and linking it to faster disability accumulation, greater cortical and brainstem pathology, and central nervous system tissue enrichment, the study shifts attention toward CNS resilience as a key determinant of long-term outcome. It also explores how smoking may worsen progression and how educational attainment may reflect a protective form of neurocognitive reserve.
