The genetics of multiple sclerosis.
Your parents’ genes came together to create your genetic makeup, and that’s exactly what gives your body directions on how to look, both inside and out. That covers everything from your hair color to your eye color to health conditions like multiple sclerosis.
According to the MS Society, there isn’t a gene that directly causes MS, but there are certain genes that may make you more susceptible. So far, researchers have found around 110 genes that are connected to MS.
However it’s not as simple as saying if you have those genes, you’ll have MS. It depends on a variety of things, including your lifestyle and several environmental factors. If you’re never exposed to those factors, then there’s a very good chance your condition will never be triggered, even if you have the connected genes.
So, your parents may pass along the genes connected to MS, but not MS, since it isn’t caused by a single gene (or even a combination of genes). That’s not to say there won’t be more than one case of MS in a family, but it’s not likely.
