RAD50

RAD50 encodes a DNA-repair protein. The surrounding genomic region also contains regulatory elements relevant to the nearby IL4, IL5 and IL13 cluster, so a locus association can concern more than the coding function of one gene.

DNA repair and a nearby Th2 regulatory region

DNA repair and a nearby Th2 regulatory region

RAD50 encodes a DNA-repair protein. The surrounding genomic region also contains regulatory elements relevant to the nearby IL4, IL5 and IL13 cluster, so a locus association can concern more than the coding function of one gene.

Putting the pieces together

Dr. Purser’s immune panel includes RAD50 through the Th2 locus-control context. Keep that immune-regulatory association distinct from a pathogenic DNA-repair finding. A nearby marker does not prove that RAD50 protein function is impaired.

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

Is my result being interpreted as a regional immune marker or a clinically classified DNA-repair variant?

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.
