Detailed Descriptions for the elements in the extension.
| Extension | |
| Element Id | Extension |
| Definition | Allele information. |
| Control | 0..1 This element is affected by the following invariants: ele-1 |
| Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (xpath: @value|f:*|h:div) ext-1: Must have either extensions or value[x], not both (xpath: exists(f:extension)!=exists(f:*[starts-with(local-name(.), 'value')])) |
| Extension.id | |
| Element Id | Extension.id |
| Definition | Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces. |
| Control | 0..1 |
| Type | string |
| Extension.extension | |
| Element Id | Extension.extension |
| Definition | May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. |
| Control | 0..* |
| Type | Extension |
| Alternate Names | extensions, user content |
| Comments | There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone. |
| Slicing | This element introduces a set of slices. The slicing rules are:
|
| Extension.extension(Name) | |
| Element Id | Extension.extension:name |
| Definition | An allele is one of a set of coexisting sequence variants of a gene (SO:0001023). This element is the common name for the allele. LOINC Code: (48008-7). |
| Control | 0..1 |
| Type | Extension |
| Extension.extension.id | |
| Element Id | Extension.extension:name.id |
| Definition | Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces. |
| Control | 0..1 |
| Type | string |
| Extension.extension.extension | |
| Element Id | Extension.extension:name.extension |
| Definition | An Extension |
| Control | 0..0 |
| Type | Extension |
| Slicing | This element introduces a set of slices. The slicing rules are:
|
| Extension.extension.url | |
| Element Id | Extension.extension:name.url |
| Definition | Source of the definition for the extension code - a logical name or a URL. |
| Control | 1..1 |
| Type | uri |
| Comments | The definition may point directly to a computable or human-readable definition of the extensibility codes, or it may be a logical URI as declared in some other specification. The definition SHALL be a URI for the Structure Definition defining the extension. |
| Fixed Value | Name |
| Extension.extension.valueCodeableConcept | |
| Element Id | Extension.extension:name.valueCodeableConcept |
| Definition | Value of extension - may be a resource or one of a constrained set of the data types (see Extensibility in the spec for list). |
| Control | 0..1 |
| Terminology Binding | EMBL-EBI database of AlleleName The codes SHOULD be taken from http://www.ebi.ac.uk/ |
| Type | CodeableConcept |
| Extension.extension(State) | |
| Element Id | Extension.extension:state |
| Definition | The level of occurrence of a single DNA Sequence Variant within a set of chromosomes. Heterozygous indicates the DNA sequence variant is only present in one of the two genes contained in homologous chromosomes. Homozygous indicates the DNA Sequence Variant is present in both genes contained in homologous chromosomes. Hemizygous indicates the DNA Sequence Variant exists in the only single copy of a gene in a non-homologous chromosome (the male X and Y chromosome are non-homologous). Hemiplasmic indicates that the DNA Sequence Variant is present in some but not all of the copies of mitochondrial DNA. Homoplasmic indicates that the DNA Sequence Variant is present in all of the copies of mitochondrial DNA. LOINC Code: (53034-5). |
