Your Child Came With a Blueprint: What a Genetic Test Can Tell You About Learning, Attention, and Detox

By Alicia Hickson, MSPAS, PA-C · Certified Functional Medicine Practitioner · Founder, Rayma Health, Minnetonka, Minnesota

A cheek swab, done once at home, reads the pathways your child’s body runs on: how their brain clears its own stress chemistry, how their body handles what is in the air and on the plate, and how they will handle common medicines someday. It does not diagnose ADHD, dyslexia, or autism, and no test can. What it does is show me how this particular child is built, so the plan fits them instead of the average kid. You read it once. It is true for life. What we do with it changes as they grow, and that is the part I love.

Why I start with how a child is built

A parent sits across from me and says one of two things. He’s bright, but he can’t sit still at school. Or: She gets a stomachache every week and nobody can tell me why.

I don’t start with a label. I start with the terrain: how this child’s body makes energy, clears chemicals, handles stress, and uses the nutrients a growing brain runs on. Genes are one map of that terrain. They are not the whole map, and they are never a verdict. But read early, they tell me where to look, which questions to ask, and which free changes at home will matter most for this child.

And this is not only for the child who is struggling. It is for the parent who wants to get ahead of it.

What a cheek swab tells me about your child

Three things I look at first. None is a verdict. All three change what I would do next.

1. Learning and attention: how the brain clears its own chemistry

Genes show how your child is wired, not what is wrong with them. Attention struggles run strongly in families, but no cheek swab diagnoses ADHD or dyslexia. What a swab does show is a tendency.

One gene, called COMT, sets how fast your child’s brain clears dopamine and adrenaline. Kids who clear it slowly tend to hold on to stress: overwhelmed in a loud room, awake replaying the day, falling apart at home after holding it together all day at school. Kids who clear it fast tend to drift when things get quiet.

Neither one is a problem. Both change what I would do: when I would put protein in front of them, what kind of movement actually settles them, and whether a supplement someone handed you fits this child. The research in children is early and points in different directions depending on the child’s age and the task, which is exactly why I treat it as a tendency and never as a label.

The number that changes a child’s week is ferritin. Genes never travel alone; I pair them with blood work. Ferritin is stored iron, and it is the first thing I check in a child who can’t focus. As a group, children with attention struggles run lower on it, and low iron is one of the most fixable things I see.

2. Detox pathways: the gene about half of kids are missing

If your child is missing a detox gene, their surroundings matter more, not less.

Your body has a family of genes that package up chemicals so they can leave. One of them, GSTM1, is simply absent in roughly half of people. Nothing is broken. It is missing the way some people are born without wisdom teeth. But it changes how much the world around your child matters.

Here is why. In a trial of children with asthma in a smoggy city, the kids missing GSTM1 were the ones whose small airways were hurt on high-ozone days, and the ones that vitamins C and E protected. Kids who had the gene were not affected either way. In a separate birth cohort, babies missing a sister gene, GSTT1, who grew up near busy roads had about twice the wheeze and asthma by age twelve. And every child is born with far less of the enzyme that breaks down common pesticides than their parents have, which is why I care more about what is sprayed on a four-year-old’s strawberries than on yours.

When I find a missing detox gene, I don’t hand you a bottle. The environment is the medicine. The list is below.

3. As they grow: medicines, gluten, and milk, answered before you need them

Know how your child handles medicines before the day you need one. This is the best-proven thing a gene test does for a child. Some kids turn codeine into morphine so fast that it is dangerous for them. Children died this way after tonsil surgery, and in 2017 the FDA made codeine off-limits for anyone under twelve. The same gene, CYP2D6, decides how a child handles atomoxetine, the non-stimulant attention medication, and the most common antidepressants. There are published dosing guidelines for each, by genotype. I would rather know before the prescription than after the side effect.

Gluten. Two immune genes, HLA-DQ2 and HLA-DQ8, tell me whether celiac disease is even possible for your child. If both are absent, celiac is almost certainly off the table for life. If one is present, it does not mean they have it; many healthy people carry one. It means we check with a simple blood test as they grow, because celiac in a kid can look like stomachaches, tiredness, or being the smallest in the class.

Milk. In kids who carry the common version of the lactase gene, the ability to digest milk sugar starts fading around age five. That is a lot of mystery stomachaches explained in one line.

What the test cannot do

I want you to hear this from me and not from a sales page. A gene is a tendency, not a sentence. A report can tell me a pathway runs slow; it cannot promise that supporting the pathway fixes your child. It cannot diagnose a learning difference, and it cannot tell me what is happening in your child’s body this month. That is what labs are for, and why the genes never travel alone.

Two things I deliberately leave out of a child’s plan, because the trial evidence does not carry them: the popular idea that an MTHFR variant means a child needs a special form of folate to focus, and the idea that a missing detox gene means more of a particular supplement. Food, air, sleep, and iron have far better evidence than either.

Three things that matter for every child, test or no test

The genes tell me where to look. This is where the real work is, and none of it costs anything.

Feed the brain first

A bowl of cereal is a blood-sugar spike with a crash scheduled for 10 a.m., and the crash looks exactly like “not listening.” Real protein at breakfast: eggs, leftover meat, a smoothie with actual protein in it. Iron-rich food a few times a week. Fish when you can. The body listens to what we feed it, and a growing brain is listening hardest.

Clean the air and the plate

Kids breathe faster, eat more per pound, and have less equipment to clear what comes in. Start with the bedroom, where they spend a third of their life: a real HEPA filter, no plug-in scents, no dryer sheets. Buy organic for the produce on the EWG’s Dirty Dozen list and don’t worry about the rest. Glass instead of plastic for anything warm. And broccoli, for every kid, not just the ones missing the gene.

Sleep, outside, and the real check-in

A school-age child needs nine to twelve hours. Protect the bedtime before anything else. Get them outside every day, in any weather we have. And once the day is quiet, ask how they are really doing. Kids carry what the house carries, and worry shows up in children as stomachaches, headaches, and “not listening.” I treat that as part of the exam, not an extra. If your child is carrying something heavy, tell me. That is a conversation I want to have.

How it works at Rayma Health

Children are welcome here. I see them with the same time, the same depth, and the same care as their parents. Here is the whole path:

1. The kit comes to your house. A cheek swab at the kitchen table, about a minute. No needles, no lab visit.
2. Results come back to me in a few weeks. I read them before you ever see them.
3. We sit down together. You, me, and your child if they are old enough. I walk you through what it means, and there is a reason for every step.
4. We add the labs that match. Ferritin, vitamin D, zinc, a full thyroid panel, and celiac antibodies if the genes say to look.
5. We touch base in four to six weeks. We retest only what was off, so we know the plan is working and not guessing.

The genes tell me where to look. The labs tell me what is actually happening right now. And sometimes the answer is your child is fine, keep doing what you’re doing. That is a good visit too.

Book a consultation

Your child is not a problem to be solved. They are a person to be understood, and you already know them better than any test ever will. The test just helps me catch up.

Frequently asked questions

Can a genetic test diagnose ADHD or dyslexia in my child?

No. ADHD runs strongly in families, but it is shaped by many genes with tiny effects, and no cheek swab can diagnose it. What the test shows is tendency: how your child’s brain clears stress chemistry and uses nutrients. A diagnosis, if one is needed, comes from a clinical evaluation.

What is the most useful thing a gene test tells you about a child?

How they will handle medicines. The gene CYP2D6 decides how fast a child turns codeine into morphine and how they process atomoxetine and the most common antidepressants. There are published dosing guidelines for each, and knowing ahead of time beats finding out from a side effect.

My child is missing the GSTM1 gene. Do they need a detox supplement?

Not from me. The trial evidence says the benefit of cruciferous foods does not depend on having the gene, so broccoli is for every child. What changes for a child missing GSTM1 is how much their surroundings matter: a HEPA filter in the bedroom, organic for the Dirty Dozen, fragrance out of the house.

How is the sample collected?

A cheek swab, done at home, in about a minute. No needles and no lab visit. It is done once; the result does not change over a lifetime.

What labs do you pair with a child's genetic results?

Ferritin (stored iron) first, then vitamin D, zinc, a full thyroid panel, and celiac antibodies if the HLA genes say to look. The genes tell me where to look; the labs tell me what is happening now.

Does the test look at adult diseases like cancer or Alzheimer's risk?

That is a decision we make together before we order. Pediatric guidelines recommend waiting on predictive results for adult-onset conditions until a child can decide for themselves, and the pathways that help me care for a child now do not require them.

Do you see children at Rayma Health?

Yes. Children are welcome, in person in Minnetonka, Minnesota, and by telehealth, with the same depth of visit as their parents.
