Either way your husband is the carrier of your childs DQ predisposition. All children you have will either have one or the other so all can be at risk :^(, But at least you know. Lets pretend there is no biopsy. What are the risk factors for CD. 1. DQ2, DQ8 DQ2/DQ8 has a 60% higher risk than either alone, 5% higher than DQ2/DQ2 or DQ8/DQ8. 2. Family member with CD. 3. Anti-gliadin antibodies 4. Associated diseases 5. Age 1 to 4 years (early onset) 30 to 40 years (late onset) The risk of CD with the type you mentioned is between 1:15 and 1:25 about 8 fold higher than the general population. The risk for a family member is 1:25 or 5 fold higher than the general population. The risk with anti-gliadin Abs abnormal is 20 fold higher than the general population. The type of antibody will be to alpha and may migrate to omega gliadin. Antibody risk factors are only germane if the individual is eating wheat at the time of serological sampling took place within a week or so. However not to disagree with the doctors, your husband sounds younger than his mid thirties, he may have not reached that 'late onset' age which converts protoCD to CD. Eating small amounts of wheat might not convert him to CD. What does the science say. Italian studies revealed that family members of CD patients with associated DQ types can convert from normal to CD spontaneously (meaning that they followed a number who were normal and in some percentage of cases they became CD). Therefore even if there were no false negatives, he is at risk, I would say pretty high risk based on above risk factors. It makes however no mention of gliadin consumption and spontaneous conversion. I hope this demonstrates the usefulness of DQ types here. If your husband failed to present either type we would eliminate the possibility(his risk would be 5% relative to yours), because he had at least one, we consider him to be a carrier, with some risk, with both types he is the carrier at higher risk. Not only that but his family members are at risk and they should also be typed. DQ type shows risk from birth to death, none of the other test can predict risk one correlate with disease. BTW just because he carried the type doesn't mean you also are not a carrier, you are still at risk since your child is CD. Aint genetics wonderful, we can track genes all over the world and cause people who worry to much to relax, and people who relax to worry. lol. Put it all into perspective. Gliadin triggers CD transglutaminase is the autoimmune target HLA DQ mediates the autoimmunity Other factors enhance autoimmunity T-lymphocytes recieve the mediation They have a big party in your GI tract. Without Gliadin DQ is not a risk factor for CD. Without HLA DQ tTG doesn't become a target of lyphocytes, paper, scissors, rock. Background (Molecular Evolution) A little info on the types. DQ2.3 is found along the western coast of europe to north africa at its highest frequency. It extends from western china to southern india and anywhere western europeans have settled. It likely moved from N.Africa to western europe via the basque to Ireland and then spread eastward to the Nordic peoples and Spread with the vikings eastward. It is the predominant type in scandinavia and western europe, Sardinia and Northern Iberia are the highest. The origin was probably N. Africa. It is not a mutant type. DQA1*0501 is found with other DQB1 and *o2 is found with other DQA1. Therefore this haplotype derived from intergenic recombination, my guess is prior to the entry of modern humans into europe >50kya. DQ8 has a sharp nodal peak in the Guayaki Indians of south America at the highest nodal frequency of any DQ type for any single people in the world with a haplotype frequency of 75%. It is found in the amazonian lowland population and declines in mexico. It is present in native peoples derived from the SE united states. In Asia the pre- yayoi (ancient) Japanese (Jomonese) appear to be the origin of the south american haplotypes, and these probably originated in Africa via Indonesia and middle east. DQ8 is one of the worlds most ubiquitous haplotypes and is found from africa to eastern and southern europe to india and the new world. It is possibly one of the humans oldest, at least 100,000 years in age, I would not be surprised if it was considerably older. Of course it is not a mutant type. DQ2/DQ8 is found in admixed populations between Iberians and Native americans in Mexico, Mesoamerica, US, South America. Even so clinicians claim that CD is not a disease of Native americans, something I strongly disagree with. It is also found at high frequencies in the finnic and swedish populations. The CD risk for the haplotype combo was determined from NW europe. The real mutants. Wheat is a polygenomic plant, it was created by the chimerization of 2 forms of wheat to form emmer's wheat, duram wheat then hybridized. There are dozens of wheat strains, all of them of human origin. It is believe that one component of modern wheat came from the indus valley, one from anatolia or europe and the third from the fertile crescent. Spelt and emmer's wheat can grow wild. Wheat like seeds are found in Isreal dating to 22,000 years ago. Their gluten content was not high. The derisably quality for wheat were grains that did not fall off and fat waxy seeds, gluten in wheat is like glue and keeps the grains coherent for harvest. Gluten has the desirous quality for storage and processed foods, particularly the omega gliadins have a tremendous glue like quality that are insoluble in water, they do not wash away. These qualities may wheat desirous for making pasta and dumplings, helps breads to rise to great heights and preserve the structure of levened bread during cooking. The protein of question is called glaidin, it is made of poly glutamine tracts and has a very unusual structure. Its a storage protein, a binding protein, a source of nitrogen for a growing plant. The quadrapeptide motif found in gliadin is a target for tTG, an unnatural target, with this target it can modify gliadin to be presented by HLA DQ and only 2 HLA DQ. It is not difficult to see that the culprit here is not the DQ, they have been around since the beginning of time, the culprit is wheat, your ancestors did not eat it, and now you do. It is a little like cows milk for asians, or alcohol for native americans, or sugar for native americans. Gluten use is on the increase, foods with higher or added gluten are becoming more common, gluten is being artificially deamidated, people are at risk for CD at a higher frequency than 100 years ago. Even so within the last 100 years people have died from CD never knowing what they had. CD was first recognized in failure to thrive childern in S. europe. The fatality rate was 50%.

Guest guest Posted December 15, 2004 Report Share Posted December 15, 2004 Philip, You know so much about the genetics of CD. When I had an amnio while pregnant with my 11 year old son, I was told that they didn't know the markers for CD. They've come a long way. Do you have any information about the prevalence in different ancestries? My husband's brother's wife is from Malaysia. Her features appear Chinese. She has the same GI symptoms as my mother- in- law with celiac, but my mother-in-law doesn't think she can have it because she doesn't have British ancestry. (Back when my husband was diagnosed, the literature we read said it was most prevalent among the British.) Thanks, Quote Link to comment Share on other sites More sharing options...

The problem is that about 1:25 persons with DQtype will have a version of CD and therefore there are other markers. Problem is that linkage analysis does not show an great linkage. > Do you have any information about the prevalence in different > ancestries? My husband's brother's wife is from Malaysia.

(Back when my husband was diagnosed, the > literature we read said it was most prevalent among the British.) The clinicians claim that Native Americans don't get CD. There is a paper out from chile claiming that indigeonous people with DQ8 do get CD. CD exists in Japan, which I believe has some higher pockets of DQ8 because of the pre-Yayoi components (22%) in that population. About 70% of Japanese genes come from Korea, the other 8% from China. There is no DQ2.3 in Japan. The level of DQ8 in Japan is several fold higher than korea and cannot be explained by chinese immigrants, therefore this serotype was present in the Pre-Yayoi population at very high frequency. Some of this came from indonesia via west pacific rim but 'DQ8' is also high in Jordon, and Japanese show some more direct genetic contribution from the middle east. Whatever the reason the gf in this region was once high. Japanese share with native americans similar HLA haplotypes A, Cw, B, DR, DQ which frequently bear the 'DQ8' (DQA1*0301:DQB1*0302). This was probably the first haplotype in the new world. I wonder does anyone here have Native American ancestry to a significant degree? I traced my DQ8 back to an NA ancestor. All Nippon Airways (ANA) changed the menu for children on its international flights because parents were complaining, from what I understand they were adding too much wheat. Native americans dn Asians don't tend to get CD because they don't eat that much wheat. When they do, they can get it. I would expect that the rise in these populations will coincide with the rise in type II diabetes in the same populations. In another recent study addressed this bias, because the europeans were claiming that CD in europeans was more severe with the DQ2.3 haplotype. A study from new york revealed that patients with DQ8 predominated the patient population and that the disease was just as severe. My concern is that some clinicians do not test certain groups of people for CD because a predisposed bias that they will not get it. Of the people I have screened the highest antibody levels were found in an african american. Remember one thing, there are gliadin allergies and intolerances. The allergies will not progress to CD but cause discomfort. In Asis the B46 allele tracts wet rice farming peoples, and there may be genetic adaptations to rice farming not associated with DQ. The only way a person can be at the greatest risk is to have the DQ type, with the possible exception of africa, in which the risk associated with all the variant types cannot be established. For example asians have Lactose intolerance because the B- galactosidase gene declines as they age. Not because of CD. They can have dermatological and respiratory problems handling wheat, such as bakers asthma. Unless a person is in the hospital with some obvious GI catastrophe, you can't diagnose CD without some sort of testing. Quote Link to comment Share on other sites More sharing options...
Guest guest Posted December 15, 2004 Report Share Posted December 15, 2004 I have seen quite a few people post in other forums whose biopsy came back negative. My personal feeling is, if he feels better, then follow the diet. That's all he could do whether he was " diagnosed " or not. I do not have an " official " diagnosis, but do know that eating gluten - even once - will cause me a great deal of gastric distress and other problems. > > I just had a frustrating day with my husband's GI Doctor.

Guest guest Posted December 15, 2004 Report Share Posted December 15, 2004 , You are amazing, thanks for your insights! We had the blood tests drawn at a different hopsital so I will have to get those results and compare them. Thanks again for your advice. Based on what you wrote, I take it that you would suggest that I get myself and my son tested as well? I am for sure recommending that my husband's 6 siblings and his parents all get screened. > Where is the IgG test? > Where is the Serum IgG test? > > Gene Test for Gluten Sensitivity > > Molecular analysis: HLA-DQB1*0201, 0302 > > > > Serologic equivalent: HLA-DQ 2,3 (Subtype 2,8) > > HLA DQ Type is HLA DQA1*0301:DQB1*0302 (DQ8)/HLA- DQA1*0501:DQB1*0201 > (DQ2.3) Good job on getting the typing done!
