.. Variant0..1ExtensionURL = http://hl7.org/fhir/StructureDefinition/observation-geneticsVariant
Variant: Variant information.


Use on Element ID Observation
... Name0..1CodeableConceptHuman Genome Variation Society (HGVS) nomenclature for a single or set of DNA Sequence Variation(s) identified in testing. The use of the nomenclature is also used to describe non-variations (aka. wild types). LOINC Code: (48004-6).

... Id0..1CodeableConceptIdentifier 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) LOINC Code: (48003-8).

... Type0..1CodeableConceptCodified type for associated DNA sequence variant. DNA sequence variants use the HGVS notation, which implies the DNA sequence variant type. LOINC Code: (48019-4).
