DNA & Epigenetics 101.

Your DNA is the instruction manual you were born with. Your epigenetics shows which instructions your body is using right now. Read together, they help explain why the plan that works for your friend may not work for you.

This page explains what a wellness DNA test can teach you, what it is not built to do, and how I use your results alongside your labs.

01 · What you learn

A wellness DNA test, explained.

My kit uses a genotyping array. Instead of reading every letter of your genome, it checks a large set of chosen positions where people commonly differ, and reads each one carefully.

The positions were picked for wellness: how you tend to process food, nutrients, caffeine, and hormones, how you recover, how you sleep. Things you can work with, or simply benefit from knowing.

The result is not a verdict. It is a list of tendencies, places where your body may run a little differently from average. That gives us better questions to ask, and a smarter place to start.

750,000

Genetic markers, approximately, focused on wellness

Your report sorts them into areas, so you can go straight to what you came for:

Metabolism
Nutrition
Vitamins & minerals
Muscle & recovery
Sleep & energy
Mood & focus
Heart & circulation
Inflammation
Detox & methylation
Hormones
Longevity

You test your DNA once. It does not change, so the results stay true for life.

02 · The line we hold

Wellness, not diagnosis.

This matters enough to say clearly. A wellness DNA test is an education tool. It does not diagnose disease, it does not screen for rare inherited conditions, and it does not replace your doctor. That boundary protects you, and it is one I hold in every session.

What we do

Look at common variants tied to everyday function: nutrients, caffeine, sleep timing, recovery, hormone clearance.
Translate tendencies into small, practical changes in food, movement, sleep, and stress.
Compare your genetics with real lab numbers, so we work from what is actually happening.
Help you prepare clear questions to take to your own doctor.

What we do not do

Diagnose, rule out, or predict any disease.
Screen for rare inherited conditions or cancer-risk genes.
Tell you to start, stop, or change any medication.
Interpret clinical findings. Those go to your doctor or a genetic counselor.

Arrays are not built for rare variants.

Genotyping arrays read common variants very accurately. For very rare variants, a large study found that most positive results were false, and concluded these chips should not guide health decisions without confirmation.³⁹

A tendency is not a diagnosis.

Results that predict risk or traits are not diagnoses. Consumer results usually need follow-up testing through a healthcare provider before they are used for medical decisions.³⁸

Your doctor runs the right test.

If you have a family history of an inherited condition, or a symptom you are trying to explain, your doctor can order clinical-grade testing, often with a genetic counselor to help you understand it.

If something in your report ever looks like it carries medical weight, I will not interpret it. I will encourage you to bring it to your doctor, and help you write down your questions first.

03 · The basics

Genetics in plain language.

A few words make the rest of this page easy.

Genome

Your full set of DNA. About three billion letters, the same in nearly every cell.

Gene

A stretch of DNA with instructions for building one working part, often an enzyme that does a job.

Variant (SNP)

A single letter where people commonly differ. Most do nothing noticeable. Some nudge how well an enzyme works.

Genotype

Which letters you carry at a spot. You have two copies of most genes, one from each parent.

No copies

The common version

Your enzyme likely works the typical way.

One copy

A mild nudge

Often a small effect, if any.

Two copies

A stronger tendency

More likely to matter, and still not a certainty.

Examples of what a report might show

Illustrations of the kind of finding a wellness report can include. Your report and your plan are personal.

CYP1A2 · Caffeine

The coffee question

This liver enzyme clears most of the caffeine you drink. Some people carry a version that clears it slowly. In one large study, heavier coffee intake was linked to higher heart attack risk only in slow metabolizers, not in fast ones.⁴¹

What we might try: earlier cutoff times, a smaller dose, and watching how your sleep responds.

GC, CYP2R1, DHCR7 · Vitamin D

Same sun, different levels

Common variants in genes that make, convert, and carry vitamin D help explain why two people with similar habits can have very different blood levels.⁴²

What we might try: checking your actual vitamin D level, then working with your provider on sun, food, and dosing.

MTHFR · Folate

Folate and methylation

This enzyme turns folate into the active form your body uses to recycle homocysteine. A common variant makes it work a little less efficiently. It is common, and on its own it does not mean something is wrong.⁴⁰

What we might try: folate-rich foods like leafy greens and legumes first, and a homocysteine lab before anyone talks supplements.

COMT, CYP1B1 · Estrogen clearance

How you clear hormones

Your liver breaks estrogen down and tags it for removal. Genes like CYP1B1 and COMT influence how smoothly those steps run, which is useful context for anyone taking or considering hormones.⁹

What we might try: fiber, cruciferous vegetables, and sharing this with whoever prescribes. Read more about hormones

04 · Biomarkers

Why different people need different things.

A biomarker is anything we can measure that tells us how your body is doing: vitamin D, ferritin, fasting insulin, homocysteine, SHBG, a lipid panel. The same habit can produce very different numbers in two different bodies. Genetics is one reason why.

Two coffee drinkers

Both have two cups before noon. One sleeps well. The other lies awake. Their caffeine clearance may be the difference, not their willpower.

Two people taking vitamin D

Same dose, same season. One lands in a healthy range, the other stays low. The lab number, not the dose, tells us which one you are.

Two people on hormones

Same prescription. One feels great, the other feels flat. How each body carries and clears hormones changes how much is actually usable.

From my own labs

More estrogen did not mean feeling better. It raised my SHBG, and my free testosterone dropped.

SHBG is a protein that carries hormones in the blood. When it rose, more of my testosterone was held onto and less was free for my muscles to use. With my medical provider, we looked at SHBG and free testosterone together. I stopped taking estrogen, because my body was already making enough. My SHBG came down and my free testosterone went up.

The lesson: the right answer was hiding in my numbers, not in a standard plan. Read the full story on the Hormones page

05 · Epigenetics

Your DNA is fixed. Your epigenetics moves.

Small chemical tags sit on top of your DNA and act like dimmer switches, turning genes up or down. The most studied tag is called DNA methylation. These patterns shift with age, and with how you eat, move, sleep, and handle stress.

Biological age

The clock

Researchers found that methylation patterns at a few hundred sites can estimate age across many tissues. This became known as an epigenetic clock.⁴³

Pace

The speedometer

Newer measures estimate how fast you are aging right now, not just where you are. One, built from two decades of follow-up, was linked with later disease and disability.⁴⁴

Change

The part you influence

Early research suggests lifestyle may shift these measures. In a small 8-week pilot trial in men, a diet and lifestyle program was associated with lower epigenetic age than controls. Larger studies are still needed.⁴⁵

3 months

One reading is a starting line. After three months, you can choose to retest your epigenetics in the portal, for an additional fee, and see what moved. Your DNA never needs retesting.

06 · Functional genomics

How I read your results.

My training is in functional genomics and nutrition. Genetics asks which variants you carry. Functional genomics asks what your genes are actually doing, and what in your daily life is shaping that. Here is how that shows up in our work.

You come first, the report second.
We start with how you feel, your history, and your labs. The genes help explain the picture. They do not replace it.
Patterns over single variants.
One variant rarely matters on its own. Several pointing at the same pathway is worth our attention.
Food and habits first.
Most findings point to something you can do at your next meal or tonight before bed. Supplements and prescriptions belong with your medical team.
One change at a time.
We pick one change, give it time, and check whether it helped. Then we choose the next.
Kind language.
You will not hear "bad genes" from me. You will hear tendencies, patterns, and places to give your body more support.
Clear referrals.
Anything that looks medical goes to your doctor, every time.

The levers we work with:

Nutrition
Movement
Sleep
Stress
Environment

07 · Not left on your own

Your DNA, plus your labs.

A portal full of results can feel like a lot. You do not have to sort through it alone.

Your genetics show tendencies. Your labs show what is happening today. Read side by side, they tell us far more than either one alone. A slow caffeine gene means more when your sleep is off. A folate variant means more when homocysteine runs high. Your comprehensive labs are how we know which tendencies are showing up in your body right now.

Included with your kit: one 45-minute review session with me. Additional 45-minute review sessions are $97.

1
Get your reports. Your DNA report arrives in about 2 to 4 weeks, your epigenetics in about 6 to 8 weeks.
2
Upload your labs. Add your comprehensive lab results in the storefront portal at portal.satinephoenix.com. Need labs? You can order panels there too.
3
I compare them. I review your DNA, epigenetics, and labs together and prepare what stands out.
4
We meet. In your review session, we choose your first change and what to watch.
5
Retest if you like. After three months, retest your epigenetics in the portal to see what moved.

08 · Your data

Questions about your data.

Where does my personal information live?

Your personal information, like your name and contact details, is kept in a HIPAA-compliant private database. Your DNA and epigenetics results are delivered to your private portal account.

Is my genetic data sold or shared with my name on it?

Our lab partner has committed in writing not to sell identifiable genetic data. Any research use is limited to de-identified data, meaning data with your name and identifying details removed.

Who can see my results?

You, and anyone you choose to authorize. I see your results only when you share them with me for your review.

Will my data be used for research or to train software?

Our lab partner may use de-identified data for research and to improve its tools. You can opt out. Ask me and I will help you do it.

Can I have my data deleted?

Yes. You can request deletion of your data. Ask me and I will connect you with the right process.

Is this a medical or diagnostic test?

No. This is a non-diagnostic wellness and educational test. It does not screen for or diagnose disease. For anything medical, please talk with your doctor.
