May is Celiac Disease Awareness month which makes this the perfect time to focus on some exciting new research in the field.

These two genes are, as geneticists like to say, "required but not sufficient." This means that you need to have them in order to get celiac disease, but, having them is not enough.
This point can be seen when you look at the amount of people who have the genetic predisposition (roughly 30-40%) and compare it to the amount of people with celiac disease (only about 1%).
So, what is it that separates the 1%...
