Gene & DNA Testing
Understand how your genes shape your health, and what to do about it
Your DNA is not your destiny. The sequence you were born with stays the same, but which genes are switched on or quieted down shifts with your diet, environment, and daily habits. That science is called epigenetics, and it is the basis of personalized wellness. As the National Library of Medicine’s MedlinePlus explains, “environmental influences, such as a person’s diet and exposure to pollutants, can impact the epigenome” [1]. In other words, the same genes can behave differently depending on how you live. At TIFAAR, gene and DNA testing gives Dr. Joseph Perlman a precise map of how your body processes nutrients, clears toxins, manages stress, and ages, so your plan is built around your biology instead of guesswork.

What gene and DNA testing tells you
Two people can eat the same diet and respond completely differently. Genetics is a big part of why. Reviews of personalized nutrition note that “individuals respond differently to the same dietary intake,” and that this variation is partly genotype-dependent [2]. Your genes carry the instructions, but gene expression, which genes are active and which are silenced, determines how those instructions actually play out. Small variations in your DNA can change how efficiently you use B vitamins, how well you clear toxins, how you respond to caffeine, and how your body manages inflammation. The caffeine example is well documented: the CYP1A2 gene is “a major caffeine metabolism enzyme, responsible for an estimated 95% of caffeine metabolism in humans,” and common variations in it explain why some people are fast metabolizers and others are slow [3].
This is the heart of what scientists call nutrigenomics: the study of how your unique genetic makeup shapes the way you respond to the food you eat. Instead of chasing the latest diet trend, it lets your plan start from the one variable that is truly yours, your genes. Our testing uses the Nutrition Genome panel, which analyzes your DNA across the systems that matter most for healthy aging. It reads variations in your genes and translates them into specific, usable guidance you can act on with your physician.
What the panel covers
The Nutrition Genome analysis reports on areas including:
- Vitamin and nutrient requirements
- Macronutrient metabolism (how you handle carbs, fats, and protein)
- Methylation, a key process behind the clearance of toxins and neurotransmitter balance
- DNA repair capacity
- Hormone and fertility pathways
- Heavy metal and pesticide sensitivity
- Cardiovascular health markers
- Mental health, anxiety, and stress management
- Sleep optimization and meal timing
- Brain and cognitive support
- Athletic performance
- A personalized grocery list built from your results
Why methylation matters
One process the panel pays close attention to is methylation. Methylation is how your body switches genes on and off, builds neurotransmitters, and clears toxins. A common example is the MTHFR gene, which makes an enzyme that converts folate (a B vitamin) into the active form your body actually uses. As MedlinePlus describes it, this enzyme “converts a form of folate called 5,10-methylenetetrahydrofolate to a different form of folate called 5-methyltetrahydrofolate” [4]. When a gene variation slows this process down, it can influence everything from energy to mood to how you handle environmental exposures. Knowing your methylation profile lets us choose the right forms of nutrients for your body rather than generic ones, for example, an already-active form of folate instead of one your body may struggle to convert.
Methylation works by attaching small chemical tags, called methyl groups, onto DNA and onto other molecules your body relies on every day. Those tags act like dimmer switches: they help decide which genes run hard and which stay quiet, and they feed the chemistry that builds mood-regulating neurotransmitters like serotonin and dopamine. The same pathway also recycles homocysteine, an amino acid that can build up when methylation runs slow. When the MTHFR enzyme works at a reduced pace, your body may have a harder time keeping that whole cycle moving, which is why a single variation can ripple out into energy, sleep, stress resilience, and how you tolerate environmental load. Because methylation depends on specific B vitamins as raw material, knowing your profile tells us which forms and amounts of those nutrients are likely to help, and which generic supplements may simply pass through without doing much. That is the practical payoff: the test turns one core pathway into clear, individualized guidance instead of trial and error.

Why DNA repair belongs in the picture
Aging well is partly about how your body maintains its own genetic code. Your DNA takes small hits every day from normal metabolism and outside exposures. As the textbook Molecular Biology of the Cell explains, “most spontaneous changes in DNA are corrected by processes collectively called DNA repair” [5]. People carry variations in how efficiently these repair systems run, and certain nutrients support the pathways involved. Looking at this area helps us understand where your body may benefit from extra support, and it is one more reason a generic, one-size-fits-all supplement plan often misses the mark.
How the process works
Simple sample collection. Testing uses an at-home cheek swab. No blood draw, no clinic visit to collect the sample.
Laboratory analysis. The lab analyzes your DNA across the panel above.
Results review with Dr. Perlman. We walk you through what your genes mean in plain language and translate the findings into an action plan.
A personalized program. Your results inform nutrition, targeted supplementation, and how we approach your other wellness goals.
Who it is for
Gene and DNA testing fits people who want to stop guessing and start personalizing. It is especially useful if you have tried diets or supplements that did not work, if you want to understand your long-term wellness tendencies, or if you simply want your wellness plan grounded in data rather than trends. It is a strong fit for anyone who feels like they are doing “everything right” and still not getting the results they want, because the answer may be hiding in how their body is wired to use nutrients.
What results can you expect?
This is a one-time test of your DNA, since your genetic code does not change. The value compounds over time, because your results guide decisions for years. Most people receive their full report within a few weeks of submitting the sample, followed by a review session to put it into action. From there, your test becomes a reference point we return to as your goals evolve, rather than a report that gets filed away and forgotten.
Why TIFAAR
Many companies will sell you a DNA report. Few pair it with a board-certified physician who uses it to build your plan. At TIFAAR, your results go straight to Dr. Joseph Perlman, a board-certified physician and former clinical faculty member at Baylor College of Medicine, who uses them as the foundation for your personalized program. The test is only as valuable as what you do with it, and that is exactly where a physician-led approach changes the outcome.
What does it cost?
Pricing depends on whether testing is part of a broader program. We review the full investment with you during your consultation.
Frequently asked questions
Is this like a 23andMe ancestry test?
No. This is a health and nutrition focused panel designed to guide a personalized wellness plan, reviewed with a physician. It is not an ancestry test.
Do I need to give blood?
No. The sample is a simple at-home cheek swab.
Will my results change over time?
Your DNA sequence stays the same. What changes is how you act on it, which is where the ongoing value comes from.
What do I get at the end?
A detailed report, a personalized grocery list, and a review session that turns the data into an action plan.
