Aussie and Kiwi researchers make double MS genetic discovery
June 15, 2009Australian and New Zealand researchers have accelerated research into Multiple Sclerosis by discovering two new locations of genes which will help to unravel the causes of MS and other autoimmune disease.
Their findings will be published today in the prestigious journal Nature Genetics.
"For decades the cause of MS has remained a mystery. This discovery reveals important new insights into the genetic susceptibility to the disease, "says Professor Trevor Kilpatrick, Director for Neurosciences at the University of Melbourne, who with Dr Justin Rubio of Florey Neurosciences Institutes coordinated the international study.
"The newly discovered gene locations in chromosomes 12 and 20, offer very promising targets which indicate susceptibility to MS," says Professor Kilpatrick.
"They also reveal a link between genetic susceptibility to MS and other autoimmune diseases including Type 1 diabetes, Rheumatoid Arthritis and Graves' Disease and the also the potential involvement of Vitamin D metabolism in the risk of developing these diseases."
"These results are like the key in the door - leading us to where to look for MS susceptibility," explains Professor Trevor Kilpatrick.
The research was conducted by members of the ANZgene consortium, more than 40 investigators from 11 institutions in Australia and New Zealand.
The three year study utilized the MS Research Australia (MSRA) Gene Bank and involved scanning the DNA of 1,618 people with MS and 3,413 people without MS (controls).
Using a genome-wide association scan (GWAS), researchers scanned the entire human genome in broad brushstrokes; looking at genetic landmarks in the genome and then progressively narrowing down their search to individual genes.
Dr Justin Rubio who coordinated the GWAS says these genetic discoveries are a major advance for the field.
"We expect that within one to two years we will be able to fine map these new regions and identify the genetic changes that underpin these findings," says Dr Rubio.
"Our next steps include studying how changes in these target genes might influence the development of MS. This work could provide insight into the development of novel therapeutics," says Dr Rubio.
MS affects some 2.5 million people worldwide and almost 20,000 in Australia. It is a devastating autoimmune disease as it occurs at the prime of life and mostly in young Caucasian women.
"This Australasian team is competing on a global scale to unravel the complex genetics of MS. This is a significant discovery" says Professor Jim Wiley, Chairman of the ANZGene consortium.
Mr Jeremy Wright, Executive Director of MS Research Australia, says: "We are thrilled to have been funding this study with the Australian Research Council and helping in its coordination. It is central to our mission of accelerating MS research to identify susceptibility in individuals so that we can potentially prevent the onset of the disease, and develop better ways to treat it".

Multiple Sclerosis Current Events and Multiple Sclerosis News RSSResearch sheds light on workings of anti-cancer drug
The copper sequestering drug tetrathiomolybdate (TM) has been shown in studies to be effective in the treatment of Wilson disease, a disease caused by an overload of copper, and certain metastatic cancers.
Multiple health concerns surface as winter, vitamin D deficiences arrive
A string of recent discoveries about the multiple health benefits of vitamin D has renewed interest in this multi-purpose nutrient, increased awareness of the huge numbers of people who are deficient in it, spurred research and even led to an appreciation of it as "nature's antibiotic."
Factors from common human bacteria may trigger multiple sclerosis
Current research suggests that a common oral bacterium may exacerbate autoimmune disease. The related report by Nichols et al, "Unique Lipids from a Common Human Bacterium Represent a New Class of TLR2 Ligands Capable of Enhancing Autoimmunity," appears in the December 2009 issue of The American Journal of Pathology.
Drug studied as possible treatment for spinal injuries
Researchers have shown how an experimental drug might restore the function of nerves damaged in spinal cord injuries by preventing short circuits caused when tiny "potassium channels" in the fibers are exposed.
CSHL team solves structure of NMDA receptor unit that could be drug target for neurological diseases
A team of scientists at Cold Spring Harbor Laboratory (CSHL) reports on Thursday their success in solving the molecular structure of a key portion of a cellular receptor implicated in Alzheimer's, Parkinson's, and other serious illnesses.
Men leave: Separation and divorce far more common when the wife is the patient
A woman is six times more likely to be separated or divorced soon after a diagnosis of cancer or multiple sclerosis than if a man in the relationship is the patient, according to a study that examined the role gender played in so-called "partner abandonment." The study also found that the longer the marriage the more likely it would remain intact.
Neurologists Investigate Possible New Underlying Cause of MS
Neurologists at the University at Buffalo are beginning a research study that could overturn the prevailing wisdom on the cause of multiple sclerosis (MS).
Scientists demonstrate link between genetic defect and brain changes in schizophrenia
Researchers at the University of North Carolina at Chapel Hill School of Medicine have found that the 22q11 gene deletion - a mutation that confers the highest known genetic risk for schizophrenia - is associated with changes in the development of the brain that ultimately affect how its circuit elements are assembled.
Gentle touch may aid multiple sclerosis patients
While gripping, lifting or manipulating an object such as drinking from a cup or placing a book on a shelf is usually easy for most, it can be challenging for those with neurological diseases such as multiple sclerosis or Parkinson's, or for people who had a stroke. For them, the tight gripping can cause fatigue, making everyday tasks difficult.
Urate in blood and spinal fluid may predict slower decline in patients with Parkinson's disease
Higher concentration of urate (an antioxidant) in the blood and spinal fluid of patients with early Parkinson's disease is associated with slower rates of clinical decline.

The MS Recovery Diet by Ann Sawyer (Author), Judith Bachrach (Author) More than half a million people live with multiple sclerosis, yet conventional medicine still has little to offer patients. There is no known cure-and even recent breakthroughs in drug therapy do not work to control many of the symptoms or promise any degree of recovery. But there is an alternative to drugs that can stop and reverse the ravaging symptoms of MS-the MS Recovery Diet. As this book explains, there are five common food triggers that can set off the symptoms of MS-dairy, grains containing glutens, legumes, eggs, and yeast. Yet because MS is such a complex disease, other foods play a role, as culprits or aides. The MS Recovery Diet explains the background, science, and development of this treatment in one source for the first time, and shows readers how to pinpoint their... |
