Vanderbilt researchers, international team, uncover genes linked to multiple sclerosis

11.08.2011
Research doubles number of genes associated with the disease

An international team of scientists has identified 29 new genetic variants linked to multiple sclerosis, providing key insights into the biology of an important and very debilitating neurological disease.

Multiple sclerosis (MS), one of the most common neurological conditions among young adults, affects around 2.5 million individuals worldwide. It is a chronic disease that attacks the central nervous system (CNS), which includes the brain, spinal cord and optic nerves, and can cause severe symptoms such as paralysis or loss of vision.

Vanderbilt University Medical Center's Center for Human Genetics Research (CHGR) played an important role in the research published today in the journal Nature, which represents the largest MS genetics study ever undertaken and effectively doubles the number of genes known to be associated with the disease.

"We now know just how complex multiple sclerosis is," said Jonathan Haines, Ph.D., director of the CHGR and one of the principal researchers in this effort. "These new genes give us many new clues as to what is happening in MS and will guide our research efforts for years to come."

Researchers studied the DNA from 9,772 individuals with multiple sclerosis and 17,376 unrelated healthy controls. They were able to confirm 23 previously known genetic associations and identified a further 29 new genetic variants (and an additional five that are strongly suspected) conferring susceptibility to the disease.

Many genes implicated in the study are relevant to the immune system, shedding light onto the immunological pathways that underlie the development of multiple sclerosis.

One-third of the genes identified in the study have previously been implicated in playing a role in other autoimmune diseases such as Crohn's Disease and Type 1 diabetes, Haines said.

Previous studies have also suggested a link between vitamin D deficiency and an increased risk of multiple sclerosis; researchers in this study identified two genes involved in the metabolism of vitamin D, providing additional insight into a possible link between genetic and environmental risk factors.

The international team led by the Universities of Cambridge and Oxford, and funded by the Wellcome Trust, includes contributions from nearly 250 researchers as members of the International Multiple Sclerosis Genetics Consortium and the Wellcome Trust Case Control Consortium.

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.

Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
