This antibody is found in ~80% of patients with coeliac disease.
Historically three other antibodies were measured: anti-reticulin (ARA), anti-gliadin (AGA) and anti-endomysial (EMA) antibodies.

It is also found in a number of patients who are not enteropathic.
Evaluating the presence of antigliadin antibodies (AGA) can be a useful complementary diagnostic test.

RCD or non-strict gluten-free diet are two causes of failure of AGA to return to normality on the GF diet.
Anti-gliadin antibodies correlate with higher risk for chronic-fatique when no clinical finding of CD is present.

IgA and IgG responses, meanwhile, like those seen to anti-gliadin antibodies in celiac disease or dermatitis herpetiformis, are not seen in response to avenins in atopic dermatitis patients.

Schizophrenia

A subgroup of persons with schizophrenia present an immune response to gluten different from that found in people with celiac, with elevated levels of certain serum biomarkers of gluten sensitivity such as anti-gliadin IgG or anti-gliadin IgA antibodies.

In bread wheat it is encoded by three different alleles, AA, BB, and DD. These alleles can produce slightly different gliadins, which can cause the body to produce different antibodies.
