Scientists think they found two key bacteria that cause multiple sclerosis

18. I believe it has a genetic component, but there are other risk factors.

You inherit a certain combination of gene alleles, which gives you a genetic predisposition to develop MS. But what triggers it (ie-environmental factors) has long been a mystery. At one time they thought it was exposure to pesticides. Now it appears that having certain bacteria in your gut microbiome is a risk factor. And those bacteria got there as a result of what you've been eating.

Interesting stuff!
By the way, something that I always thought was funny regarding medical genetic research. Looking at sets of identical twins has always been the 'Holy grail' for these kinds of studies. If you have an identical twin, you'll be hounded by scientists for your entire life to volunteer for studies.

Another funny thing about medical genetic research is that Salt Lake City Utah was always the Mecca of genetic research. Mainly because the Mormons practiced polygamy. And, to avoid accidentally marrying your second cousin, the Mormons kept extremely detailed family trees (pedigrees). Those are great for identifying diseases with a genetic component. For all the trash talking people do about Mormons, we owe them a debt of gratitude. A huge chunk of what we know about diseases with genetic components came from the Mormons volunteering their family pedigrees for genetic research.
