    Wanted to let you know how much I enjoyed Tuesday evening's webinar on Emerging Therapies. The speaker was fabulous and I left with much information. If this is an indication of future Can Do MS webinars, I will sign up for all! Thank you again for organizing the webinar and keeping the MS community abreast of needed information.

    Researchers Recruiting 5,000 First-Degree Relatives of People with MS for Genetic/Environmental Research Study

    Posted Wednesday, October 26, 2011

    News from the National MS Society

    Researchers from the Harvard Medical School, Brigham and Women's Hospital, and Partners Multiple Sclerosis Center are recruiting 5,000 subjects who have at least one first-degree relative with a diagnosis of MS. The goal of the study is to identify the genetic, environmental and immune profiles that may increase a person's risk of developing MS. A first-degree relative could be a parent, sibling, or child of a person with MS, and the study is limited to those between 18 and 50 years of age. The GEMS (Genes and Environment in MS) study is led by primary investigator Philip De Jager, MD, PhD, a Harry Weaver Neuroscience Scholar of the National MS Society. The study is privately funded.

    Background: An individual's risk of developing MS increases several-fold if a close family member has MS. There is currently no way to predict which family members will develop MS. Genetic, environmental and immunologic studies to date have identified key markers that are associated with the risk of MS. The GEMS Study is gathering genetic material (DNA) and environmental exposure history from participant as well as blood samples and brain Magnetic Resonance Imaging (MRI) as an option. Investigators are testing the performance of new method of identifying persons at risk for MS. Identifying high-risk individuals will influence the design of effective preventive strategies for MS.

    The Study: Investigators are recruiting 5,000 first-degree relatives of MS patients. A first-degree relative could be a parent, sibling, or child between 18 and 50 years of age. The first-degree relative may or may not have an existing diagnosis of MS, but must have the ability to provide consent and be willing to participate in the study.

    All 5,000 participants are being asked to donate a saliva sample for DNA analysis (sent via mail, at no cost to the participant) and complete a questionnaire online about neurologic history, family history and potential environmental exposures. Based on answers to this questionnaire and the DNA analysis, the team will be collecting blood samples and MRI scans from a subset of participants who chose to participate in that part of the study. The team will contact all participants every three years for up to 20 years to obtain an updated questionnaire.

    There is no cost to participate in the study, and participants can reside anywhere in the United States because no travel is required to enroll in the study. Some travel may be required for the optional MRI portion of the study and the participant will be reimbursed for travel cost.

    All participants are assigned a unique study identification number to ensure complete confidentiality.

    Using this information, the investigators plan to pinpoint specific genetic, environmental, and immunologic factors that may increase a person's risk of developing MS. These findings may allow for earlier intervention to slow down MS or help to develop strategies for preventing the disease.
