IL18R1

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

The binding side of the IL-18 receptor

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

Putting the pieces together

Dr. Purser connects this receptor pathway with celiac and inflammatory bowel disease contexts. A gene for receiving a signal is distinct from the gene that produces it. Symptoms and standard diagnostic testing should determine whether a gut inflammatory disorder is present.

Where the VARS Triad and MTHFR Daily fit

If you are exploring homocysteine or cytokines, Dr. Purser may discuss MTHFR Daily and the VARS Triad: VARS Glutathione, VARS SOD, and VARS Catalase. He gives glutathione a central place in his approach to antioxidant support.

A gene result alone cannot tell you that you need these products or that they will treat a condition. Review your current results, medicines, goals, and tolerance with your clinician before choosing a product or dose.

A question to bring to your visit

Are we investigating a confirmed gut inflammatory condition or only a susceptibility marker?

Variant lookup

These names can help you find an entry on your original genetic report. Seeing a name here does not tell you whether it affects your health or whether you need treatment.
