Encodes diamine oxidase, an enzyme involved in breaking down histamine and other amines. DAO is used here as an enzyme nickname; it is also the official symbol of a different gene.

ATG16L1 is involved in autophagy, a process that helps cells recycle parts.

BHMT helps recycle homocysteine into methionine using betaine. It is a different route from the folate and B12 pathway.

CHDH helps convert choline toward betaine, a nutrient involved in the homocysteine pathway.

FOLH1 helps break down folate from food so it can be absorbed. This is different from the MTHFR step.

FUT2 affects substances on the surfaces of the gut and other moist tissues and is studied in relation to the microbiome.

HLA-DQA1 contributes to an HLA-DQ protein that presents antigen fragments to CD4 T cells. HLA-DQ function depends on pairing with an HLA-DQB chain, so an isolated marker is not a complete HLA type.

IL23R encodes part of the receptor that receives IL-23 signals. This connects the gene to the maintenance of Th17-related immune responses, which differ from the Th2 patterns discussed in allergy.

Makes an enzyme involved in producing phosphatidylcholine, a component of cell membranes. Genetic findings alone do not establish a choline deficiency.

IL18R1 encodes a component of the receptor for IL-18. It works with an accessory component, IL18RAP, to support IL-18 signaling.
