Genetic Links to MS Found
It keeps being reported that "scientists have found two genes for MS." What does this mean? I'll try to shed some light on this. The first statement is confusing, as it implies these genes "cause" MS, in the same way that certain genes directly cause birth defects or other problems. Instead, the "MS genes" work to increase susceptibility to MS, meaning that other factors are still at work. This just means certain people with these genes are 20 to 30 percent more likely to have MS. Put it this way: If the overall risk of MS in the US is 1 in 1000, and you have these genes, your risk becomes 1 in 770. Read more about Risk Factors for MS
