Extension: DNA sequence variant ID

URL for this extension:

http://hl7.org/fhir/StructureDefinition/observation-geneticsDNAVariantId

Status: draft. Extension maintained by: Health Level Seven International (Clinical Genomics)

Identifier for DNA sequence variant. If a germline variant, ClinVar or dbSNP identifier should be used. If a somatic variant, COSMIC identifier should be used, unless in ClinVar then either maybe used. Need to provide the code system used (ClinVar, dbSNP, COSMIC) LONIC Code: (48003-8).

Context of Use: Use on element: Observation
