IL21 encodes a cytokine involved in regulating lymphocytes, including B-cell responses. It sits within an immune network that connects T-cell help, antibody responses and inflammatory activity.
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.
IL6 encodes interleukin-6, a cytokine involved in immune responses and acute-phase signaling. It can appear in discussions of infection, chronic inflammation and metabolic health, with effects that depend on the context.
MAOA helps break down some chemical messengers. A gene result cannot predict a mood or behavior.
MTHFD1 helps move folate between forms used for different jobs in the body.
The homocysteine chapters include MTHFD1L in the wider folate-related genetic map.
Makes an enzyme that helps produce a form of folate used in the processing of homocysteine. Common variants are different from rare variants that cause severe MTHFR deficiency.
Makes the methionine synthase enzyme, which uses vitamin B12 in the conversion of homocysteine to methionine.
Helps maintain the activity of methionine synthase, connecting B12-related chemistry with homocysteine metabolism.
