Our genomic reference data

Atlas data

Public facts about genes, variants and traits, as JSON. No account and no key: none of it is about you.

Gene, variant and trait pages and the genome search as JSON: the facts each page shows, every link an absolute url. Public and read-only, with no key; any origin may read it.

Each path is also its page's URL without .json, asked for with Accept: application/json.

These are reference facts about genes, variants and traits, not anyone's results: cite the page's url, and don't present a classification as a diagnosis.

Search

Genes, variant pages and conditions by any name or ID, and what lies at a place in the genome. Search first unless you already have a page's URL: follow each hit's url or json rather than building a path. A query not asked before is a live search, so searches are metered per client.

Your AI assistant reads your own results once you sign in to the Genome Manager. Read-only, and only ever your data.

Read-only tools over a Dante Labs member's own genome, once they sign in and pick a profile.

MCP access comes with Premium + AI. Every tool call checks the membership, so access ends when it does.

Tools

`whoami`

Read-only

Connected profile

Returns the connected Dante profile (id, name, email) and subscription tier for this MCP session.

`get_ancestry`

Read-only

Ancestry

Continental genetic ancestry for the connected profile: top population and posterior probabilities (AFR/EUR/EAS/SAS/AMR/OCE). Used to interpret variants and calibrate predictive tools.

`list_prioritised_conditions`

Read-only

Prioritised conditions

Top clinically prioritised conditions found in the connected profile genome, ranked by aggregate score. Returns MONDO id, disease name, variant count and scores. Note that one variant can match several MONDO ids, so entries here are not necessarily distinct findings — call list_prioritised_variants and read each variant's mondoMatches to see which rows share a single underlying variant.

Argument	Description
`topNinteger 1–100`OptionalDefault 20	How many to return, highest scored first

`list_prioritised_variants`

Read-only

Prioritised variants

Top clinically prioritised variants in the connected profile genome. Returns locus, gene, consequence, zygosity (with copies spelling out whether this is one copy or two; this data does not carry the condition's inheritance mode, so one copy is carrier status only if the condition is recessive — for a dominant one it can be enough to cause it), ClinVar id and significance, per-disease mondoMatches with the significance ClinVar assigned for each disease (a variant labelled pathogenic overall may be only a risk factor for a given condition) and, when ClinVar classified it for a subtype of that disease rather than the disease itself, the subtype as classifiedFor, HGVS, gnomAD allele frequency (null when the backend has none) and score. Includes variants on ACMG secondary-findings conditions at any frequency (acmgSecondaryFinding on the match) and other variants only when rare; a rare variant outside the ACMG list has an uncertain link to the person's health and should be presented that way.

Argument	Description
`topNinteger 1–100`OptionalDefault 20	How many to return, highest scored first

`get_pharmacogenomics`

Read-only

Pharmacogenomics

The connected profile's pharmacogenomics report: for each pharmacogene it calls from single-variant (SNV/indel) data, the star alleles carried and the diplotype and (for activity-score genes) activity score behind CPIC's phenotype, what CPIC says that phenotype implies for each drug (drug, population, implication, strength; never a dose), the drugs CPIC pairs with the gene, and PharmGKB's clinical annotations. Read ambiguous and assumedReference before quoting a phenotype: the first means the loci could not be resolved cleanly, the second that no variant was called and the result rests on the reference allele — read it against referenceAllele.function. A gene with no phenotype (VKORC1, CYP4F2) reports its alleles only. notCalledFromThisData names the pharmacogenes this report deliberately does not call (CYP2D6, G6PD, HLA-B, …) and why — do not infer anything about those from a missing entry.

Argument	Description
`locale"en""de""es""fr""it""ar"`OptionalDefault "en"	The language of the report's text

`get_theme_report`

Read-only

Wellness theme report

One of the connected profile's wellness theme reports — fitness, nutrigenetics or sleep — laid out as the report itself is: chapters of findings (one variant each: gene, rsID, the reader's genotype, copies of the effect allele, and the result, finding and what the reader can do), alerts, advice that applies to this reader, and notes, with references. Each finding's status says whether it describes the reader (reported), the reader carries an allele the report does not describe (uncharacterised), or the site could not be read (not_analysed). An alert's status is triggered or clear when the reader was assessed, and uncharacterised or not_analysed otherwise. Quote a finding only when reported, and an alert only when triggered or clear.

Argument	Description
`reportstring`Required	Report slug, e.g. fitness, nutrigenetics or sleep
`locale"en""de""es""fr""it""ar"`OptionalDefault "en"	The language of the report's text
