READING THE PANELS

First — how to read one of these rows.

Every card on the other spokes is the same three-beat translation the rest of this site uses: the gene and the letters I carry, the mechanism in the report’s language, then how that can show up.

SHORT VERSION

Read the row the same way you read a scan.

  • A letter change is not a disease.
  • The report rates how strongly a row might contribute — that is its language, not mine.
  • I translate mechanism first, then how it can show up. I do not invent missing fields.
THE GLOSSARY

A few words get used a lot. Here they are once.

This is not a diagnosis.

IntellxxDNA describes itself as a clinical decision-support tool for licensed providers — one input next to a full history, an exam, and labs — not something meant to diagnose or treat illness on its own. Nothing on these pages is a diagnosis. These are small DNA changes that by themselves are not disease-causing. They can matter as they interact with each other and with diet, lifestyle, and environment.

SNP

A single-letter change in the DNA sequence.

Minor allele

The less common version of the sequence. It can convey benefit or risk — it is not automatically bad.

Genotype / result

The two letters actually carried, one allele inherited from each parent.

Copies

0, 1, or 2 minor alleles. Two copies generally means a stronger effect.

Prevalence

How common this exact genotype is in the population.

Impact

The report’s own Low / Medium / High rating for likelihood and strength of contribution.

Odds ratio

1.0 means no difference from baseline. 2.79 means roughly 2.79× the reference risk. Printed for some SNPs only.

Homozygous

Both copies are the same.

Pharmacogenomics

Using genotype to predict how someone will respond to a specific drug.

WHAT I DID

I learned the translation before I argued with a row.

No supplement starts on this spoke. The intervention here is literacy: same three beats as the scans, jargon defined on first use, missing fields left blank.

CROSS-CHECK

A primer does not overlap an image.

NO OVERLAP

How to read a row is not a SPECT or QEEG finding. The other two instruments live on their own pages. I am not forcing a match.

KEEP GOING

The adjacent threads sit one click away.

How it works is the primer. The library is the index. The other spokes are the payload.
