Because one disease of the DNA problem explained above can be caused by certain foods (hormones or stress), I wonder if gluten was the trigger for me. It is possible when I get chapped lips from eating gluten that this problem with my lips happens due to DNA mutation. Since I had the vitamin A deficiency from celiac disease, I do not know if it is a combination of this DNA problem triggered by certain food (gluten in my case) AND vitamin A deficiency.
I can't believe this came up in my DNA when I was not even looking for it. I wrote many posts about skin glue (adhesion) and here it shows up in my DNA as a gene mutation!
