Anti-transglutaminase antibodies result in a form of gluten sensitivity in which a cellular response to Triticeae glutens that are crosslinked to tTG are able to stimulate transglutaminase specific B-cell responses that eventually result in the production of anti-transglutaminase antibodies IgA and IgG. [36] [37] tTG specifically deamidates the ...
The endomysium contains a form of transglutaminase called "tissue transglutaminase" or "tTG" for short, and antibodies that bind to this form of transglutaminase are called endomysial autoantibodies (EmA). [6] The antiendomysial antibody test is a histological assay for patient serum binding to esophageal tissue from primate.
These peptides are modified by tTG in two ways, deamidation or transamidation. [80] Modern anti-tTG assays rely on a human recombinant protein as an antigen. [92] tTG testing should be done first as it is an easier test to perform. An equivocal result on tTG testing should be followed by anti-endomysial antibodies. [21]
The IgG antibody is similar to AGA IgA, but is found at higher levels in patients with the IgA-less phenotype. It is also associated with coeliac disease and non-celiac gluten sensitivity. [5] [6] [7] Anti-gliadin antibodies are frequently found with anti-transglutaminase antibodies.
Reported symptoms of NCGS are similar to those of celiac disease, [30] [31] with most patients reporting both gastrointestinal and non-gastrointestinal symptoms. [29] [32] In the "classical" presentation of NCGS, gastrointestinal symptoms are similar to those of irritable bowel syndrome, and are also not distinguishable from those of wheat allergy, but there is a different interval between ...
IgA deposits may form if the antibodies cross-react with epidermal transglutanimase (eTG). Some patients have eTG-specific antibodies instead of tTG-specific cross-reactive antibodies and the relationship between dermatitis herpetiformis and celiac disease in these patients is not fully understood.

Pronunciation follows convention outside the medical field, in which acronyms are generally pronounced as if they were a word (JAMA, SIDS), initialisms are generally pronounced as individual letters (DNA, SSRI), and abbreviations generally use the expansion (soln. = "solution", sup. = "superior").
