Not a medical test — for research and educational use only

Yeliztli analyses consumer genotyping-array data (23andMe / AncestryDNA), which is not a clinical-grade test. Results are not diagnostic, are not clinically validated, and must not be used to make medical decisions. Array data is especially unreliable for rare, disease-causing variants. Always confirm any finding with an accredited clinical laboratory and discuss it with a qualified clinician or genetic counsellor before acting on it. See the Intended use & disclaimers page for the details and the evidence behind this warning.

Export your data in several formats from the variant table or from Query Builder results:

Format	Description
VCF 4.2	Standard variant call format
TSV	Tab-separated, with all annotation columns
JSON	Structured JSON with nested annotations
CSV	Comma-separated, for spreadsheets
FHIR R4	DiagnosticReport Bundle (JSON) in the FHIR R4 genomics-reporting format, for interoperability with research/genomics tooling — not a clinical diagnostic report (see below). Nuclear variant coordinates are exported in the GRCh37/hg19 reference frame; mitochondrial coordinates use rCRS.

Exports reflect whatever filters or query you have applied, so you can export a focused subset rather than your whole genome.

The FHIR export is not a clinical diagnostic report

The FHIR R4 export produces a DiagnosticReport resource using the standard genomics-reporting format, purely for interoperability with research/genomics tooling. It is research/educational, array-derived, and not clinically validated — it is not a clinical diagnostic report and must not be filed as a clinical result or used to drive clinical decisions. To make this unambiguous to any receiving system, the bundle is marked status: "preliminary" and carries the research-use caveat in the DiagnosticReport.conclusion field. Confirm any finding with an accredited clinical laboratory.

Variant Observation resources use 1-based genomic coordinates and include a LOINC-coded genomic reference-sequence component for the GRCh37/hg19 nuclear build or the rCRS mitochondrial reference, so chromosome positions are not exported as reference-ambiguous values.
