2 ywar old has celiac and I found out I have the genetic marker for it.

Hi all- I've posted a few times concerning my 2 year olds positive celiac blood test. She has all the symptoms of it- the worst is the projectile vomiting and clay colored D mixed with C. I had a blood test to see if I have it and its turns out im a carrier. I have the marker that potentially can turn into celiac one day as well. Ive had lifelong GI issues.

Does anyone know anything esle about the genetic marker- DQ2?
