Variant evidence review

Stop at ambiguity before classification or literature lookup

A plausible-looking HGVS string is not enough to identify a unique genomic allele. Assembly, transcript version and reference sequence can matter. Safe agents branch on the returned state and never choose a candidate by guesswork.

Agent question

Can this public HGVS expression be resolved to one supported GRCh38 allele?

Deterministic state handling

Continue only for a resolved result. For ambiguous results, show returned candidates and ask the user to select. Report not found, invalid, unsupported and temporarily unavailable states directly.

Prevent identity drift

Do not substitute a nearby variant, silently change assembly, remove a transcript version or search literature for a guessed allele.

  • Echo the exact input
  • Record the declared assembly
  • Preserve transcript and version
  • Show returned candidates without ranking them
  • Continue only after explicit disambiguation
