description: Details about a set of changes in the tested sample compared to a reference 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: category: mustSupport: true index: 1 slicing: slices: labCategory: match: {} schema: pattern: type: CodeableConcept value: coding: - {code: laboratory, system: 'http://terminology.hl7.org/CodeSystem/observation-category'} index: 2 elements: coding: {index: 3} referenceRange: {short: Not used in this profile, index: 14} hasMember: {short: Not used in this profile, index: 15} method: {mustSupport: true, index: 12} specimen: type: Reference mustSupport: true refers: ['http://hl7.org/fhir/us/mcode/StructureDefinition/mcode-human-specimen'] index: 13 value: mustSupport: true choices: [] index: 10 component: mustSupport: true index: 16 slicing: slices: allelic-state: match: {} schema: mustSupport: true index: 45 elements: code: {mustSupport: true, index: 46} value: mustSupport: true choices: [] index: 48 molecular-consequence: match: {} schema: mustSupport: true index: 61 elements: code: {mustSupport: true, index: 62} value: mustSupport: true choices: [] index: 64 genomic-source-class: match: {} schema: mustSupport: true index: 37 elements: code: {mustSupport: true, index: 38} value: mustSupport: true choices: [] index: 40 copy-number: match: {} schema: mustSupport: true index: 65 elements: code: {mustSupport: true, index: 66} value: mustSupport: true choices: [] index: 68 variation-code: match: {} schema: mustSupport: true index: 49 elements: code: {mustSupport: true, index: 50} value: mustSupport: true choices: [] index: 52 genomic-hgvs: match: {} schema: mustSupport: true index: 25 elements: code: {mustSupport: true, index: 26} value: mustSupport: true choices: [] index: 28 amino-acid-change-type: match: {} schema: mustSupport: true index: 57 elements: code: {mustSupport: true, index: 58} value: mustSupport: true choices: [] index: 60 cytogenetic-location: match: {} schema: mustSupport: true index: 21 elements: code: {mustSupport: true, index: 22} value: mustSupport: true choices: [] index: 24 sample-allelic-frequency: match: {} schema: mustSupport: true index: 41 elements: code: {mustSupport: true, index: 42} value: mustSupport: true choices: [] index: 44 protein-hgvs: match: {} schema: mustSupport: true index: 53 elements: code: {mustSupport: true, index: 54} value: mustSupport: true choices: [] index: 56 cytogenomic-nomenclature: match: {} schema: mustSupport: true index: 29 elements: code: {mustSupport: true, index: 30} value: mustSupport: true choices: [] index: 32 gene-studied: match: {} schema: mustSupport: true index: 17 elements: code: {mustSupport: true, index: 18} value: mustSupport: true choices: [] index: 20 coding-change-type: match: {} schema: mustSupport: true index: 33 elements: code: {mustSupport: true, index: 34} value: mustSupport: true choices: [] index: 36 effectiveDateTime: {type: dateTime, mustSupport: true, index: 8} status: {mustSupport: true, index: 0} effective: mustSupport: true choices: [] index: 7 code: {mustSupport: true, index: 4} subject: type: Reference mustSupport: true refers: ['http://hl7.org/fhir/us/mcode/StructureDefinition/mcode-cancer-patient'] index: 5 dataAbsentReason: {mustSupport: true, index: 11} package_version: 3.0.0-ballot class: profile kind: resource url: http://hl7.org/fhir/us/mcode/StructureDefinition/mcode-genomic-variant base: http://hl7.org/fhir/uv/genomics-reporting/StructureDefinition/variant version: 3.0.0-ballot
