Hereditary alpha-tryptasemia
doesn't stop at the skin.

HαT is a copy-number variant of the tryptase gene that turns up the volume on the mast cell system — and follows the body wherever mast cells live: brain, vessels, gut, bone, barrier.

Precision medicine effect vs. standard care
The sentinel biology
Extra TPSAB1 copies were an evolutionary advantage — faster immune response, higher vigilance. The same biology that protected your ancestors is overloaded in a modern, mineral-depleted, high-trigger world.
The cascade
Tryptase → connective tissue degradation → craniocervical instability → glymphatic impairment → neuroinflammation → autonomic dysregulation → POTS. One modifier. One cascade. Ten diagnoses.
The question
What if the most common cause of treatment-resistant ADHD, POTS, and multi-system illness in American families is a $50 blood test away from having a name?

Hypothesis · Open Call

A trial worth running.

What if ADHD and autism share an upstream driver we've been missing — and the protocol that's moving the needle in early Alzheimer's could move it here too?

The precedent

A 2025 precision medicine RCT in early cognitive decline reported 5–7× improvements in neuroinflammatory outcomes where standard care declined — by treating root causes instead of symptoms.

The pattern

ADHD carries an inflammation signal. Autism carries a mast cell signal. Both run through the same neighborhood. HαT provides a genetically identifiable, measurable upstream driver of exactly the microglial dysfunction that defines both.

The upstream suspect

HαT turns up the mast cell volume system-wide — including the brain's. A $50 basal serum tryptase identifies carriers. BST has never been measured in treatment-resistant ADHD or ASD cohorts.

Same protocol. New disease.

  1. Identify the genetic driver
  2. Stabilize mast cells
  3. Quiet neuroinflammation
  4. Settle the autonomic nervous system
  5. Correct the copper / nutrient axis
  6. Restore sleep architecture

Every piece of this exists in the literature. The bundle has never been tested in ADHD or ASD. That's the gap. That's the ask.

Not medical advice. A call for a trial, not a treatment claim.

Research Gap 29–35 · The Copper Axis

The modifier has a modifier.

Copper is not a peripheral detail. It is an essential cofactor for four independent mechanisms that each directly compound HαT severity — none of which have been studied in HαT-confirmed cohorts.

Mechanism 1 · Connective tissue

LOX — Lysyl Oxidase

Copper-dependent enzyme that crosslinks collagen and elastin into mechanically strong matrices. Low copper → LOX fails → collagen synthesized but not crosslinked → structurally weak tissue that cannot resist chronic tryptase-driven proteolysis. Same mechanism confirmed in keratoconus corneas (2.5× lower LOX activity) and progressive myopia.

PMID 9587142 · PMID 23041260
Mechanism 2 · Tryptase expression

MITF — Tryptase Gene Brake

Copper inversely regulates the MITF transcription factor and its downstream target, the tryptase gene, via ERK1/2 signaling. Copper sufficiency suppresses tryptase gene transcription. Copper deficiency removes this brake — tryptase-positive mast cell numbers expand. In HαT carriers, this amplifies an already constitutively elevated tryptase burden.

Lunderius-Andersson et al. J Immunol 2017 · PMID 29127151
Mechanism 3 · Histamine clearance

DAO — Diamine Oxidase

Diamine oxidase is the primary enzyme responsible for degrading histamine in intestinal tissue and plasma — and it is copper-dependent. Low copper impairs DAO activity. In HαT carriers already producing excess mast cell-derived histamine, copper-insufficient DAO means histamine accumulates from two directions simultaneously: excess production and impaired clearance.

Mechanism 4 · Autonomic / POTS

DBH — Dopamine-β-Hydroxylase

DBH is the cuproenzyme that converts dopamine to norepinephrine in sympathetic nerve terminals. Low copper impairs DBH → reduced norepinephrine synthesis → autonomic dysregulation clinically indistinguishable from POTS. Copper deficiency also reduces tyrosine hydroxylase neurons in the dorsal motor nucleus of the vagus — the brainstem's parasympathetic brake — the same structure HαT neuroinflammation is already compromising.

Critical: causal direction

Copper deficiency worsens HαT. HαT does not predictably deplete copper — inflammation tends to raise serum copper via ceruloplasmin upregulation. Serum copper alone is insufficient to assess status in an inflamed HαT carrier. The correct panel is: serum copper + ceruloplasmin + RBC copper/SOD activity + serum zinc + DAO activity. RBC copper is the most sensitive functional marker. Zinc supplementation — common in MCAS self-management — competitively depletes copper and may be inadvertently worsening mast cell reactivity via MITF derepression.

The copper panel that starts to answer this:

Serum copper Ceruloplasmin RBC copper / SOD Serum zinc DAO activity

One blood draw. The study does not exist. Yet.

37 research gaps.

Each one testable. Most requiring only a $50 blood draw and the will to ask the question.

Gap 1
HαT prevalence in treatment-resistant ADHD and ASD
BST and ddPCR genotyping in treatment-resistant ADHD cohorts vs. treatment-responsive controls. Whether HαT predicts stimulant failure. Maternal BST as predictor of ASD risk in offspring.
Unstudied
Gap 6
HαT and craniocervical instability — the central mechanistic question
Upright MRI in HαT-confirmed carriers. Companion in vitro study measuring tryptase exposure effects on craniocervical ligament tissue. The most important gap for validating the core cascade hypothesis.
Unstudied
Gap 15
HαT neuroinflammation and treatment-resistant aggression
FDA's 2026 approval of dextromethorphan/bupropion for Alzheimer's agitation validates NMDA antagonism for neuroinflammatory agitation. HαT is the same upstream mechanism with no treatment pathway. BST in aggression cohorts — unstudied.
Unstudied
Gap 29
Copper status in HαT carriers
Serum copper, ceruloplasmin, RBC copper, zinc, and DAO activity have never been measured in a confirmed HαT cohort. Whether copper status predicts connective tissue severity, BST level, or phenotypic expressivity — unstudied.
Copper Axis
Gap 34
HαT and cluster B personality disorders
BPD shows elevated HPA dysregulation, autonomic dysfunction, elevated CRP, and impaired prefrontal regulation — the same biological fingerprint as HαT neuroinflammation. BST has never been measured in cluster B cohorts. Directly testable. Potentially transformative.
Unstudied
Gap 35
HαT as a modifier of NAFLD and NASH
Reduced hepatic copper is confirmed in pediatric NAFLD with steatosis severity inversely correlated to copper levels (n=150, p<0.001). The copper-mitochondrial-hepatic cascade, tryptase-driven cytokines, and HPA cortisol dysregulation may all converge in HαT carriers. HαT prevalence in NAFLD cohorts — unstudied.
Copper Axis
Gap 36
MOTS-c — The Mitochondrial Distress Signal
MOTS-c is the peptide mitochondria release when copper-iron depletion starves cytochrome c oxidase. In HαT carriers running a high-alert Sentinel system on a failing mitochondrial battery, MOTS-c may be constitutively dysregulated. Plasma levels have never been measured in HαT-confirmed carriers. The assay is standard. The question has never been asked.
Bioenergetic
Gap 39
GLP-1 Agonists and the Glymphatic Axis
GLP-1 receptor agonists reduce neuroinflammation, improve mitochondrial function, stabilize the BBB, and enhance glymphatic clearance of CSF toxic metabolites — directly addressing the HαT neuroinflammatory cascade. GLP-1 receptors are expressed on mast cells. Whether HαT-confirmed carriers show differential GLP-1 response — unstudied.

Why this exists.

Tryptase Place started in a kitchen, with a mother, a notebook, and a stack of symptoms that no single specialty would claim. It exists now because the science keeps catching up — and because the people living this deserve maps, not maybes.

The screening test exists. The cost is under $50. The cycle ends here.
