Can you have celiac disease without having the genes for it?

This topic raises much debate. The current thought shared by the many physicians and scientists is that 1-2% of celiacs may not possess the celiac-specific genes HLA-DQ2 and/or DQ8. Our Dr. Guandalini and Dr. Bob Anderson, chief scientific officer of ImmusanT, believe the genes are necessary to initiate the immunologic response of celiac disease, hence… Read more »

Do most people with celiac disease have the gene turned on at birth?

For celiac disease to develop, you don’t just need the gene(s), but also the contribution of several environmental factors (the first one being gluten, of course), hence the fact that celiac disease can appear at any time and at any age for those who have the gene(s).

How is genetic testing different than antibody testing for celiac disease?

Blood tests, such as the tissue transglutaminase test (tTG) or the antiendomysial (EMA) antibody test, measure the autoimmune response triggered by gluten that occurs at that particular point in time. These are important tests because they characterize the extent to which the immune system is responding to gluten. Unlike antibody testing, the HLA genetic test… Read more »
