<<Disclaimer: Verify this information before applying it to your situation.>> If the readers of this listserv group are interested in the question of whether or not celiac disease seems to strike one blood type more than another, I am a Ph.D. (ABD) at the University of Wisconsin and teach statistics in the graduate program. I would be happy to conduct an impromptu survey and see how our blood types compare to the known percentages in the population. If you have celiac disease or gluten intolerance and you know your blood type, drop me an email message and tell me a) your blood type [A, B, AB, O] as well as your Rh factor [positive or negative]. If there are others in your family with CD or GI, you may include their blood types as well. If I get enough responses to do the analysis, I will post the results to the group. BJ
