Amazing about your sister. Eva, I forget how you Found Out about this mutation issue. I have a friend who has awful gastro issues and she is such a clean food person and takes hardly any drugs and just wondering about this mutation with her. I don't know her early life history with stomach but I'll mention it to her. She's so tired of tests etc. and is getting too old to keep testing and testing. She takes DGL, probiotics and digestive enzymes and still has issues. Makes me wonder. C
