description: An alteration in the most common DNA nucleotide sequence. The term variant can be used to describe an alteration that may be benign, pathogenic, or of unknown significance. The term variant is increasingly being used in place of the term mutation. Variants can be computed relative to reference sequence assembly from which it was identified. package_name: hl7.fhir.us.mcode derivation: constraint name: GenomicVariant type: Observation elements: referenceRange: {short: Not used in this profile, index: 7} hasMember: {short: Not used in this profile, index: 8} method: binding: {strength: extensible, valueSet: 'http://loinc.org/vs/LL4048-6'} mustSupport: true index: 5 specimen: type: Reference mustSupport: true refers: ['http://hl7.org/fhir/us/mcode/StructureDefinition/mcode-genomic-specimen'] index: 6 value: short: Whether the variant is present choices: [valueCodeableConcept] index: 2 component: mustSupport: true index: 9 elements: code: {mustSupport: true, index: 10} value: mustSupport: true choices: [] index: 12 slicing: rules: open description: Slice based on the component.code pattern discriminator: -
