The researchers believe that multiple sclerosis is a disease caused by Multiple Sclerosis genetics and environmental factors. MS genetics research has brought about the discovery that the differences between individual genes may increase the risk of developing Multiple Sclerosis. For example, a person who has a family member with MS, the disease is more likely to be diagnosed within an immediate family member as well. It seems that the highest percentage of risk is between children, parents, and siblings. So a person who is a twin has a probability of 35 percent to be diagnosed with MS as well. But, a half-brother or sister has only a 5 percent chance of being diagnosed positive with the disease.

Studies have shown a certain group of genes may be a factor in causing MS. The genes on chromosome 6 appear to increase the likelihood that a person will develop Multiple Sclerosis. Apart …
