Researchers Seeking Black Americans with MS to Participate in Genetics Studies

 Help Find Clues to the Cause and Treatment of MS
 
Researchers at the University of California MS Genetics Project are studying how MS affects Black Americans with MS. The university maintains a unique repository of DNA and other biological materials with the support of the National MS Society.

Why Does This Matter? New research shows that more Black people are diagnosed with MS than previously thought and that they may have a different disease course. Genes are known to play a role in determining who is susceptible to developing MS and may also influence the severity and course of the disease. Identifying the exact location of MS genes could help determine who is at risk for developing the disease and may provide clues to its cause, prevention, and better treatment.
Focusing on Black, Hispanic/Latinx, Northern European, and other ancestral groups, and searching for what is common and what is different in their DNA sequences may help identify the precise genetic variants that contribute to MS.

What is involved?  It is not necessary to travel to San Francisco to participate in this study. Once an individual has completed the initial online intake form and has agreed to participate, they are emailed the links to two additional online forms and sent a kit via express mail.

The kit includes a consent form, a health information privacy form, and a medical records release form. The kit also includes everything necessary for the blood draw, which can be taken to your local Quest Diagnostics Lab, where the blood can be drawn and then returned in a prepaid envelope to the UCSF MS Genetics Lab. There is no cost to the study participants. 

Individuals recently diagnosed with MS living in the San Francisco Bay Area are also eligible to participate in an MRI study to identify relationships between genetic profiles and tissue damage in the brain and spinal cord.

Researchers Recruiting People with Primary Progressive MS for Genetics Studies – Key to finding treatment options

Primary progressive MS is characterized by steadily worsening neurologic function from the onset of the disease. There are still many gaps in the knowledge we have about what differentiates relapsing-remitting from primary progressive MS, and the underlying mechanisms of primary progressive MS. The MS Genetics Group at the University of California San Francisco is recruiting people with primary progressive MS for a research study involving a one-time blood sample donation with the goal of identifying genetic factors driving the course of the disease. The team also is looking for people without MS who are not related to serve as controls. The team hopes to identify the major genetic factors that play a role in disease presentation and progression. Please note: you do not have to be located in or travel to California to participate. Everything for the study can be done remotely and is free of charge to participants.

Rationale: Specific subtle variations in the human genome are known to play a role in determining who is susceptible to developing multiple sclerosis, and may also influence the course of the disease. People living with MS can make a difference in studies searching for these genes by donating their DNA with a blood sample. Identifying the exact location and role of MS genes could help determine who is at risk for developing the disease and can provide clues to its cause, prevention, and lead to better treatments.

Details: Once an individual has completed the initial online intake form, they will receive a call from the study coordinator to discuss details and answer any questions. The consent form and health information privacy form can be signed electronically. Participants will then be emailed a link to two additional short online surveys and sent a blood-collection kit. The kit includes everything necessary for the blood draw, which can be taken to your local Quest Diagnostics Lab and returned in a prepaid envelope to the lab at UCSF. There is no cost to participants.

Gene That Boosts Resistance to Malaria linked to Susceptibility to MS and Lupus in Sardinia

Researchers from Italy found a strong association between the gene that instructs the molecule “BAFF” and susceptibility to MS and lupus in studies of nearly 6,000 people in Sardinia. The BAFF gene is crucial to activation of immune B cells and is also associated with resistance to malaria. Malaria was common in Sardinia until it was eradicated in 1950. The rates of MS and certain immune-mediated diseases are high in Sardinia. Further research is necessary to confirm whether this high rate is related to BAFF, and whether MS could be treated by a therapy that targets BAFF.

New research strengthens genetics, MS link

In a large-scale, genome-wide analysis of more than 110,000 samples, researchers identified 200 genetic loci associated with multiple sclerosis. The study authors said that while the research highlights the role of several different immune cells that contribute to the initiation of this inflammatory disease, the mechanisms that lead this inflammatory disease to target the brain and spinal cord remain unclear.
By comparing the genomes of people with and without MS, the researchers identified 200 variants that were significantly more common among those with the disease. Most of these variants implicate genes that are associated with immune cells and immune system function, including a few potentially specific to brain-related functions.
Interestingly, many of the genes identified were known to also be involved in other autoimmune diseases, such as rheumatoid arthritis, Type I diabetes, and ulcerative colitis. This raises intriguing questions about why these diseases target different organs and have different clinical manifestations.
The findings were presented at the American Society of Human Genetics (ASHG) 2016 annual meeting in Vancouver, B.C.

Study Shows Expansion of Stem Cell Clinics in the U.S. and the Need for Better Oversight

Researchers have published a paper describing the proliferation of stem cell clinics in the United States and ethical issues and regulatory concerns that come with marketing unproven treatments for many conditions. Their study shows that many different types of unproven stem cell treatments are being offered, and highlights concerns for the safety of people who undergo these treatments.

There is exciting progress being made through innovative research related to the potential of many types of stem cells for slowing MS disease activity and for repairing damage to the nervous system. At present, there are no approved stem cell therapies for MS. People need the best available information to understand this exciting area of research and make decisions related to this complex issue.

The paper’s findings support the need for stem cell therapy to be explored in the context of carefully conducted clinical trials that can determine what the optimal cells, delivery methods, safety and actual effectiveness of cell therapies might be for people with MS.

Study finds greater role for environment in MS

Environmental factors may be playing a much greater role in the onset of multiple sclerosis than previously realized, according to early research led by Queen Mary University of London and Barts Health NHS Trust. The theory is based on new findings showing that Black people and South Asians in east London have a higher prevalence of MS compared to those groups in their ancestral countries, indicating a strong environmental influence on the disease that could be driving higher MS rates in London.

The researchers, led by Dr. Klaus Schmierer, used electronic records from general practices in four east London boroughs (Tower Hamlets, Newham, Hackney and City of London) which were reviewed for the number of MS-diagnosed patients, grouped by ethnicity. What they found was that MS appeared to be several times more prevalent among African people and South Asians living in London compared to those groups living in their ancestral territory. While prevalence differences could be explained by fewer MS diagnoses occurring in less resourced countries, the authors said it is unlikely to explain the gulf in prevalence between these territories. They said that an alternative, or additional, explanation would be increased exposure in the UK to environmental agents or behaviors that facilitate the development of MS.

Lead author Schmierer said, "MS is a disease where genetic ancestry and environmental factors play a role, however to what degree these two aspects are driving the risk of developing MS remains unknown. We found that people of Asian and African extraction in London are far more likely to have MS than people of the same ethnicity living in their ancestral countries. Our early results suggest that environmental factors play a pivotal role in the risk of developing MS, whilst the individual genetic backdrop may be of lesser importance."

The study was published in Multiple Sclerosis Journal.

Scientists fault gene mutation for inflammation

A new mouse model study has identified a faulty "brake" within immune cells, one that should control inflammation, and points to a potential target for developing new therapies to treat multiple sclerosis. The results suggest new research models of multiple sclerosis symptoms such as movement disorders and balance control problems.

A mutation in the gene Nlrp12 was causing a malfunction in T cells. Normally, the protein the gene produces acts as a brake within T cells to control the inflammatory response. But a mutation in that gene disrupts the natural process and provokes severe inflammation. The resulting inflammation produced MS symptoms such as movement disorders and problems with balance control.

Results of mouse model studies sometimes do not translate to humans and may be years away from being a marketable treatment. However, according to researcher John Lukens, Ph.D., of the University of Virginia School of Medicine, "It's important to note that MS is a spectrum disorder - some patients present with paralyzing conditions and some patients don't. Not everybody's symptoms are the same, so this might give us a glimpse into the etiology or pathogenesis of that family of MS."
