Coeliac disease

celiac diseasecoeliacceliac
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.

Gluten-sensitive enteropathy–associated conditions

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.

Common wheat

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.

Protein

Some of these antibodies can detect proteins in specific grass taxa such as Triticeae (Triticeae glutens), while others react sporadically with certain species in those taxa, or over many taxonomically defined grass tribes.

Triticeae

Some of these antibodies can detect proteins in specific grass taxa such as Triticeae (Triticeae glutens), while others react sporadically with certain species in those taxa, or over many taxonomically defined grass tribes. The target of the most allergenic antibodies is ω-5 gliadin, which is encoded by the Gli-1B gene found on the B haplome (Aegilops speltoides derived) of wheat.
