Researchers have discovered several genes that play a role in multiple sclerosis. The new study out of Yale University looked at nearly ten thousand MS patients, and compared them to seventeen thousand healthy control subjects. Researchers identified twenty-nine new gene variants that appear to play a role in the disease, and confirmed nearly two dozen discovered in past studies. Several of the genes are known to cause other auto-immune diseases, like type one diabetes. Researchers say this study will guide future research and treatments for patients with MS. Researchers say the environment also plays a role in a patient's risk for MS. For example, vitamin D deficiency has been linked to multiple sclerosis.
