- Donor-specific pathological features associate with genetic background, lesion type distribution, and clinical heterogeneity in multiple sclerosis
People with MS differ widely in how the disease behaves, partly because of differences in their genetic makeup. Using brain tissue donated by 287 people with MS, researchers examined whether specific tissue features tied to a person's genetic background relate to the mix of lesion types and to how severe their disease was. Connecting inherited differences to what is actually seen in the brain helps explain why MS varies so much between individuals and could improve how doctors predict its course.
- The HLA paradox across populations in multiple sclerosis progression: a systematic review
The strongest known genetic risk factor for developing MS is a version of the immune gene HLA called DRB1*15:01, which roughly triples susceptibility. But whether it also speeds up the disease once it begins has been debated. Pooling 56 studies covering more than 22,000 people, this review found only a modest, inconsistent link between HLA variants and MS progression. The work clarifies that genes which raise the risk of getting MS don't necessarily determine how fast it advances.
- Immune-Related Gene Variants as Modifiers of Multiple Sclerosis Severity
MS is a polygenic disease, many genes each add a small amount of risk, and researchers want to know which ones shape how severe it becomes. In 548 untreated Russian patients, this study tested 35 variants in immune-system genes against a standard MS severity score. Variants in several genes (including CCR5 and the major risk gene HLA-DRB1) were linked to severity. Findings like these move toward genetic tools that could one day help predict an individual's likely disease course.
- Epigenetic and genetic insights for tailored therapeutic strategies in multiple sclerosis
Multiple sclerosis risk is shaped by both genes and environment, and treatments that work well for one person may not for another. This review pulls together what's known about the genetics of MS, more than 200 risk regions in the genome, with the HLA-DRB1*15:01 immune gene the strongest, alongside epigenetic changes (chemical marks that switch genes on or off) and environmental triggers like Epstein-Barr virus. The goal is more personalized MS care, using a person's genetic and molecular profile to guide which disease-modifying therapy is most likely to help.
- Lifespan Modeling of Choroid Plexus Volume in Multiple Sclerosis and Its Dynamic Associations With Clinical, MRI, and HLA Susceptibility
The choroid plexus, a structure that makes spinal fluid, enlarges early in MS. Studying 727 patients and 461 healthy people, researchers modeled how its size changes across the lifespan and linked enlargement to clinical features, MRI findings, and genetic risk, including HLA and broader polygenic risk scores. Tying a measurable brain structure to inherited MS risk could yield new ways to identify higher-risk patients and understand how genetic susceptibility plays out in the brain.
- Identification of an immunogenic epitope from RASGRP2 with specificity for HLA-DR15 in multiple sclerosis
In multiple sclerosis the immune system attacks the brain, but exactly what it targets has been hard to pin down. This study focused on people who carry HLA-DR15, the immune-gene variant most strongly tied to MS risk, and searched for pieces of a protein called RASGRP2 that their immune cells recognize. Identifying such gene-linked targets is a step toward "tolerising" therapies designed to calm the specific immune response in genetically susceptible patients, a more precise alternative to broadly suppressing immunity.
- Association Between Multiple Sclerosis Severity and Functional Variants in Key Antioxidant Defense and Ferroptosis-Related Genes
Why multiple sclerosis progresses faster in some people than others may partly reflect their genes. Researchers genotyped 845 MS patients (relapsing-remitting and progressive) for variants in genes that defend cells against oxidative stress and a form of cell death called ferroptosis, both linked to nerve damage in MS. By testing whether these variants track with the progressive form of the disease, the study looks for inherited factors that influence severity, which could eventually help identify who is at greater risk of worsening.
- Integrating Genetics and Environment to Find Causal Mechanisms for Multiple Sclerosis
Genome studies have found hundreds of DNA regions that raise multiple sclerosis risk, but not how they actually cause disease. This review explains how scientists are connecting those risk variants to biology, especially by mapping which variants change how genes are switched on in specific immune cells, and how genetic and environmental risks (like Epstein-Barr virus) may converge on shared pathways. Turning a list of risk genes into real mechanisms is essential for designing treatments that target the roots of MS rather than only its symptoms.

- Type 1 Diabetes and Multiple Sclerosis Share General Autoimmunity Genetic Variation
Multiple sclerosis and type 1 diabetes are both autoimmune diseases and sometimes occur in the same person or family, hinting at shared genetic roots. Using large genetic datasets (nearly 15,000 MS patients and many more for diabetes), researchers looked for DNA regions that influence both conditions and identified 26 shared signals. Understanding this common "autoimmunity" genetics helps explain why these diseases cluster together and could point to treatments or prevention strategies that work across more than one autoimmune condition.
- Differential Roles of IL-18 and IL-8 Gene Variations in Multiple Sclerosis: Associations with Susceptibility and MRI Disease Activity
The immune signaling molecules IL-18 and IL-8 help drive the inflammation seen in multiple sclerosis, and small inherited differences in their genes might affect who develops MS and how active it is. This study compared 98 people with relapsing-remitting MS to 98 healthy volunteers, looking at variations in these two genes and relating them to disease susceptibility, disability scores, and MRI activity. Findings like these add to the picture of how a person's immune-gene makeup shapes their individual course of MS.
