I was diagnosed 2 years ago with Celiac after being misdiagnosed for many years. I had gall bladder surgery with complications and was told that triggered the Celiac. My gastro doctor said it was the worst case of Celiac he had seen. All of my villi (sp?) were completely flat, not one left standing. Both of my parents have now had the blood test for Celiac and both were negative. Two of my children have tested negative. My brother and sister have yet to be tested. In my extended family (aunts, uncles, cousins), no one has had any symptoms, so no tests for any of them. If both of my parents have tested negative, where did the gene and disease come from? I would appreciate a response from anyone who could shed some light on this. And thank you in advance for your help.
