Researchers believe Multiple Sclerosis is a disease caused by a number of MS genetic and environmental factors. Multiple Sclerosis genetic factors aren’t considered to be hereditary causes of MS, but certain variations among a person’s genes might possibly increase the risk of developing MS. For instance, an individual who already has a family member with Multiple Sclerosis is more likely to be diagnosed with MS as well. It seems the highest percentage of risk lies between parents, children, and siblings. So a person who is a twin has a 35 percent chance of being diagnosed with MS if his/her twin sibling has tested positive for MS, while a half sibling has only a 5 percent chance of being diagnosed with the disease.

Studies have shown a specific group of genes might be a factor in causing MS. The genes in chromosome 6 seem to increase the probability that a person …
