A gluten allergyânot to be confused with gluten sensitivity or celiac diseaseâis caused by gliadin, a glycoprotein that, along with glutenin (another protein), helps to form the gluten protein. Gluten is found in wheat and other related grains such as barley, oats, and rye.Gliadin is also one of the major allergens associated with wheat allergies and a trigger for celiac disease, a serious autoimmune disorder of the small intestine.Unlike a gluten allergy, in which small amounts of gluten may be tolerated, a patient with celiac disease cannot tolerate any gluten at all.liadin is also one of the major allergens associated with wheat allergies and a trigger for celiac disease, a serious autoimmune disorder of the small intestine.
