What to watch with HLA-DQ2 and allergy?

The question about HLA-DQ2 and allergy is relevant, but the provided context lacks any specific studies or data on this topic. HLA-DQ2 is strongly associated with celiac disease (human-strong evidence), not with typical allergies like pollen or food allergies. Some research explores a link to wheat allergy or atopy, but the evidence is weak and inconsistent. Direct-to-consumer tests like MyBody-X can detect HLA-DQ2, but interpreting it for allergy is speculative. An allergy test (IgE) or a physician consultation is more reliable. Caveat: a positive HLA-DQ2 result does not imply an allergy. Clinical relevance is unclear. Evidence: human-moderate for celiac, but for allergy it is mechanistic/unclear.
