Plan B · in plain English

Where the bottleneck is:
your kid's cleanup engine

When you hear “your kid is a poor methylator,” it sounds like jargon. It isn't. It's the single most useful thing to understand about why they're sick — and why they get better.

The big idea: take out the trash

Every body makes trash all day — leftover junk from fighting infections, from food, from normal metabolism. A healthy body hauls it away before it piles up.

Methylation is the body's main trash truck. It's a chemical process running billions of times a second in every cell. It does three big jobs: makes brain chemicals(serotonin, dopamine), calms inflammation, and hauls waste out.

In a lot of PANS-spectrum kids, the trash truck runs slow. So when infections and gut bugs make extra trash, it doesn't get carried away fast enough. It backs up. And some of that backed-up trash lands in the brain — where it shows up as OCD, rage, anxiety, and sleep problems.

That's “a poor methylator.” Not too many infections — too little cleanup. Many problems, one bottleneck.

This is the part that changes the plan: you can kill infections with antibiotics or herbs — and sometimes you should. But that's you doing the clearing for your kid. If the cleanup engine stays broken, the bugs (and the trash they make) keep piling back up, and you're killing one infection after another forever. The bigger win is helping the body clear them itself — fixing the engine so your kid stops relapsing.

The diagram: where it jams

Read it top to bottom. Trash comes in, the engine processes it, and it either clears — or backs up.

TRASH COMES IN

Infections (Bartonella, strep, mold) · toxins · food · normal metabolism

creates a load: homocysteine, histamine, amines, quinolinic acid

THE ENGINE — the methylation + detox cycle

Folate in

jam point: MTHFR — activates folate

Methylfolate

jam point: MTR / MTRR — recycle B12

Methionine SAMe

jam point: COMT / MAO — clear dopamine, serotonin, histamine

Homocysteine Glutathione

jam point: CBS — the sulfur gate (master detox)

Each arrow is an enzyme step. A “slow” step (a SNP) is a jam point. Each step needs a cofactor (B12, B6, zinc, magnesium, molybdenum) to run.

WHEN IT WORKS

Brain chemicals balanced · inflammation calm · toxins out. Kid is steadier.

WHEN IT BACKS UP

Quinolinic acid rises in the brain OCD · histamine builds anxiety · homocysteine climbs · poor detox flares

Three ways to see the bottleneck

You can't fix a jam you can't see. Three tests look at it from different angles — and they stack, they don't compete.

Walshblood panel — the SNAPSHOT

Reads what the chemistry is doing right now: over- or under-methylated (whole-blood histamine), copper overload, zinc deficiency, pyroluria. These chemistries directly cause OCD, rage, and anxiety. Tells you WHAT to correct today.

Yasko / StrateGene23andMe $99 — the BLUEPRINT (DIY)

Reads the genetic instruction manual for the cycle — which steps are slow (MTHFR, CBS, MTRR, COMT, MAO). Tells you WHY, and the order to support it (CBS-first for kids who clear poorly). Cheap, self-orderable, covers the core methylation genes.

IntellxxDNApractitioner report — the EXPANDED, CURATED map

A clinician-curated genomic report that goes far beyond methylation — detox (phase I/II), neurotransmitters, nutrients, immune, cardiovascular — with decision-support a practitioner reads with you. The upgrade when you want curated breadth and a guided plan, not a DIY raw file.

Walsh = now. Yasko = the core wiring (cheap, do-it-yourself). IntellxxDNA = the full curated map (practitioner-grade). Start with Walsh + 23andMeStrateGene; add IntellxxDNA when you want a curated, guided read.

Worked example: undermethylation (the most common PANS pattern)

Lots of PANS kids — the OCD, perfectionist, “it has to be just right,” high-inner-tension, rigid/ritualistic type — are undermethylated. Plain version: the methyl-donor side of the engine runs low, so the brain has a harder time keeping serotonin and dopamine working, and histamine runs high. That's the engine behind the OCD and the rigidity.

Here's what each of the three tools does for an undermethylated kid specifically:

Walshconfirms it + the nutrient fix

A high whole-blood histamine is the fingerprint of undermethylation. Walsh's undermethylation protocol leans on methionine/SAMe, B6, zinc, magnesium, and calcium — plus one critical DON'T: avoid folic acid / high folate, which makes undermethylators worse. Walsh tells you your kid is undermethylated and which nutrients correct it.

Yasko / StrateGenethe genetic reason + how to dose it

Shows which steps are slow — MTHFR, MTR/MTRR (B12 recycling), BHMT (the betaine backup route), COMT, MAO. This personalizes the fix: a slow COMT means methyl donors can make the kid wired and irritable, so you go low-and-slow; a BHMT issue points to TMG/betaine instead. Without this you're guessing the dose — and methyl donors done wrong backfire.

IntellxxDNAthe curated full map to fine-tune

A practitioner-read report that adds the downstream genes (neurotransmitter clearance, detox, nutrient transport) and how they interact — so the methyl support is tuned: not too much (wired), not too little (no effect). The upgrade when the basic picture isn't enough to dose confidently.

Together for an undermethylated kid: Walsh says “yes, undermethylated” and gives the nutrient protocol; Yasko + IntellxxDNA say why and how to dose it safely (especially the COMT “go gentle” caveat). Methyl support done wrong can backfire — which is exactly why you test instead of guess.

Why this is the hopeful part

Here's the catch that changes everything: you can't change the genes, but you can feed each slow step the exact nutrient it's missing. A weak MTHFR enzyme works fine when you give it the active form of folate. A jammed CBS gate needs different support. The tests tell you whichnutrient, so you're not guessing.

Infections come and go. The cleanup engine is the foundation — the layer that's actually fixable, and the one almost no specialist checks (PANS care grew out of neurology, immunology, and infectious disease — none of which trains on this biochemistry). Get it supported and your kid clears better, flares less, and you stop chasing one symptom after another.

Cheapest first step: 23andMe Ancestry ($99) + free StrateGene + a Walsh blood panel. Upgrade to IntellxxDNA for a curated, practitioner-guided read. Have questions for your kid? Ask Minta — she can walk you through what these would likely show given what's already in the file.
