PON gene mutation
By Russell Browne (Dip. Adv. Nut.) · Specialist in Genetic Nutrition & Methylation Protocols
The PON changes discussed here — usually in PON1 — are common polymorphisms (variants), not rare defects. This page covers what the PON gene does, what the research supports, and what we observe in practice.
What is a PON gene mutation?
A PON “mutation” — more accurately a common gene polymorphism or variant — is a widespread variation that can influence how this gene and its enzyme work. These are common variants that shift relative likelihoods, not switches that determine your health.
What the PON gene does
PON1 provides instructions for paraoxonase 1, an enzyme carried on HDL (“good” cholesterol) that has antioxidant activity and helps break down certain compounds, including some organophosphate chemicals. It is studied both for its antioxidant role and for how individuals process particular substances.

Bad Genes – The Genetic Advantage by Russell Browne is a plain-English tour of the common gene variants that most influence health — the ideal companion to your variant report, and a great place to see how the individual genes fit together.
PON1, antioxidant activity, and processing compounds
Common PON1 variants (such as Q192R and L55M) are associated with differences in the enzyme’s activity. Researchers have examined these in relation to antioxidant capacity, cardiovascular measures, and how people handle certain chemical exposures. Effects are modest and shaped by many other factors.
PON Variants: What the Research Shows, and What We See in Practice
There is a lot written about these genes online, and much of it overstates the case. We separate two kinds of information: what the published research has found, and — kept distinct from it — the patterns we have observed in clinical practice.
What the research shows
PON1 variants have been studied for associations with enzyme activity, antioxidant/cardiovascular measures, and the metabolism of certain compounds, with modest and variable findings.
Three things are essential to keep in view about this research:
- These variants are common — a large share of the population carries them.
- The findings are associations — relative shifts in likelihood across groups — not causation. A variant does not, by itself, cause any condition.
- Many people who carry these variants experience none of the associated patterns. Genes are one influence among many.
What we observe in clinical practice
In practice we treat PON1 as one input among many when considering antioxidant status and exposures — never as a stand-alone diagnosis or a reason to act on a genotype alone. This is a clinical observation used case by case, reviewed with appropriate testing and a practitioner.
How to find your PON result
Your existing 23andMe or AncestryDNA raw data file already contains your PON markers — you do not need a new test. Uploading it produces a plain-language variant report showing your PON result (and many others), which you can then review with your practitioner in the context of your whole health picture.

Important note
This page is educational and is not a diagnosis or a treatment plan. These variants are common and shift relative likelihood, not certainty; many people who carry them experience none of the patterns described here. The clinical observations reflect what we have seen in practice and will not apply to everyone. Anything you wish to act on should be assessed individually with a qualified practitioner who can consider your full history, symptoms, and any relevant testing.

Treating PON gene mutations
If you suspect you may have symptoms related to the PON gene mutations or you want to prevent these conditions, the first thing to do is get your ancestry raw data and upload it to our app, this will show your PON genes and provide the status of the mutations.
Once you confirm if you have PON mutations the best thing you can do is work with a practitioner who understand epigenetics and nutrigenomics via a consultation here.
