Extension Gene - Detailed Descriptions

Detailed Descriptions for the elements in the extension.

Extension
Definition

A region (or regions) that includes all of the sequence elements necessary to encode a functional transcript. A gene may include regulatory regions, transcribed regions and/or other functional sequence regions (SO:0000704). This element is the official gene symbol approved by the HGNC, which is a short abbreviated form of the gene name (HGNC). LOINC Code: (48018-6).

Control0..1 This element is affected by the following invariants: ele-1
Comments

Other systems or genes not defined in HGNC (e.g., BCR-ABL fusion gene) can be added by using a local extension.

InvariantsDefined 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
Definition

unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

Control0..1
Typestring
Extension.extension
Definition

May be used to represent additional information that is not part of the basic definition of the element. In order 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 is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.

Alternate Namesextensions, 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.

SlicingThis element introduces a set of slices. The slicing rules are:
  • unordered
  • Open
  • discriminators: value:url
Extension.url
Definition

Source of the definition for the extension code - a logical name or a URL.

Control1..1
Typeuri
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.

Extension.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).
