First-degree relatives of multiple sclerosis (MS) patients may develop asymptomatic disease, suggesting the need to further evaluate family members to develop timely prevention strategies. The study, “Investigating early evidence of multiple sclerosis in a prospective study of high risk family members,” was presented at the Americas Committee for Treatment and…

Small natural variations within the DNA sequence of the gene for interleukin-16 (IL-16) were linked to an increased susceptibility to multiple sclerosis (MS) in a small group of Iranian patients. The study, “The Association of Interleukin-16 Gene Polymorphisms with IL-16 Serum Levels and Risk of Multiple Sclerosis,” was published in…

A genome-wide study has identified DNA regions associated with higher levels of circulating cytokines, small proteins that pay a role in inflammatory diseases such as multiple sclerosis (MS). Alterations in the levels and interplay of cytokines and growth factors play a key role in several inflammatory diseases, including MS. Cytokines help regulate…

The key to why more women than men develop multiple sclerosis (MS) may be genes that influence physical traits, such as weight, height, and body shape, according to a new study. Researchers caution that the findings need to be verified, but they said processes leading to disease may differ between…

Family members of multiple sclerosis (MS) patients who are asymptomatic but at a higher risk of developing the disease themselves are more likely to have early signs of the disease, according to a study published in JAMA Neurology and titled "Assessment of Early Evidence of Multiple Sclerosis in a Prospective Study of Asymptomatic High-Risk Family Members". These people should therefore be closely monitored.

A new study confirmed the involvement of three genetic variants, or mutations, of the interleukin-23A (IL-23A) gene, and one variant of its receptor IL-23R,  in the risk of developing multiple sclerosis (MS) and other related inflammatory nervous disorders, together known as inflammatory demyelinating diseases (IDD). Details of this study, “Characterization of…

Here’s my Pick of the Week’s News, as published by Multiple Sclerosis News Today. Immune System May Harbor Natural Way of Fighting MS, Other Autoimmune Diseases A genetic key to a possible natural way of battling MS could be worth further work. A variant in the TYK2 gene, which encodes…

Researchers in Russia found for a first time an association between variants in GAL, a gene that codes for the galanin protein, and multiple sclerosis (MS). Importantly, they also found that this association is sex specific. The study, “Single-nucleotide polymorphism rs948854 in human galanin gene and multiple sclerosis: a…

In multiple sclerosis (MS) patients who do not respond to interferon-beta treatment, autoimmunity may depend on processes that differ from patients helped by this treatment— a finding that could lead both to better therapies and tests that predict a patient’s likely response. The study, “An interferon-β-resistant and NLRP3…

A variant in the TYK2 gene, which encodes an immune system protein, may work to protect people from autoimmune disorders, including multiple sclerosis (MS), without overly depressing the body’s ability to fight opportunistic infections, researchers at the University of Oxford report. Their study, “Resolving TYK2 Locus Genotype-To-Phenotype Differences In Autoimmunity,” was published…

A genome-wide analysis of over 110,000 people allowed researchers with the International Multiple Sclerosis Genetics Consortium (IMSGC) to discover 200 genetic loci (the position of genes on a chromosome) that are common to people with multiple sclerosis (MS). The findings were given in the presentation, “200 loci complete the genetic puzzle of multiple sclerosis,” by Dr. Nikolaos…

Genes that encode what are called “complement” immune factors are linked to the breakdown of the retina in multiple sclerosis (MS) patients — a measure that, in turn, predicts brain damage and loss of eyesight. The study, a joint effort between researchers from Johns Hopkins School of Medicine,…

Multiple sclerosis seems to be less severe in people with higher levels of the minor adult hemoglobin variant A2 (HbA2) in their blood, according to a team of Turkish researchers. This could be due to this variant having a higher protective effect on the red blood cell membrane. The authors speculate that HbA2 could therefore be playing a role in reducing long-term neural injury in MS.

In the largest genetic study ever performed in a single country, scientists in Germany discovered four new risk genes for multiple sclerosis (MS). The genes, altered in MS patients, are involved in the control of how other genes are activated through mechanisms known as epigenetics. The discovery advances understanding of how…

Regions of DNA called super-enhancers regulate immune cell activity, including the body’s response to threats like inflammation or pathogens, and now scientists have found that they also harbor genetic variants associated with autoimmune diseases — gene variants that may be the “master switches” for these conditions. The findings were described in the study “…

Some forms of multiple sclerosis are hereditary after all. After many years of saying that MS is not passed down the generations, new research now says the opposite. Although past studies have suggested that genetic risk factors could increase the risk of developing the disease, up until now, there has been…

A single genetic mutation in a gene called Nr1h3, can cause familial multiple sclerosis (MS), reported scientists from the University of British Columbia and Vancouver Coastal Health. The study, “Nuclear Receptor NR1H3 in Familial Multiple Sclerosis” was published in the journal Neuron. The discovery…

Researchers detected the expression of the gene ANKRD55  in immune cells, a gene that has been previously linked to multiple sclerosis (MS) in mice models of the disease. The results suggest a potential role of ANKRD55 in MS pathogenesis. The study, “Novel Insights into the Multiple Sclerosis Risk Gene ANKRD55,”…

Children whose mothers were vitamin D deficient during the early stages of pregnancy are at an elevated risk for developing multiple sclerosis (MS) in adulthood, according to a study published in the journal JAMA Neurology, titled “Vitamin D Status During Pregnancy and Risk of Multiple…

A Spanish study showed that relapse and remission in multiple sclerosis (MS) states are regulated by small non-coding RNA (sncRNA) molecules in patterns differing between men and women. Scientists have increasingly realized that sncRNAs play an important role in the regulation of gene expression. Various kinds of these RNA molecules, such as…

A research team at Brigham and Women’s Hospital (BWH) in Boston and the National Institute of Neurological Disorders and Stroke (NINDS) launched a study on people at risk for developing multiple sclerosis (MS), a debilitating disease that affects more than 400,000 people in the United States and about…

Researchers at the University of California, San Francisco, (UCSF) are asking African-Americans with multiple sclerosis, as well as family members, to participate in new studies into the genetic origins of the disease. The studies will investigate both people of African ancestry with MS, who are known to have low susceptibility for the disease, and those of Northern European descent,…

A Colombian study reported finding an increased risk of multiple sclerosis (MS) associated with a particular allele, or gene variant, in a group of patients from the Colombian capital, Bogotá. The study also found a protective allele — HLA-DRB1*14 — that might explain the low rates of MS observed throughout the…
