May change in future releases. See Maturity Model.
Computational Definition
Representation of a variation by a specified nomenclature or syntax for a Variation object. Common examples of expressions for the description of molecular variation include the HGVS and ISCN nomenclatures.

Description |
|---|---|---|---|---|
id |
string |
0..1 |
The ‘logical’ identifier of the data element in the system of record, e.g. a UUID. This ‘id’ is unique within a given system, but may or may not be globally unique outside the system. It is used within a system to reference an object from another. |
|
extensions |
⋮ | 0..m |
A list of extensions to the Entity, that allow for capture of information not directly supported by elements defined in the model. |
|
syntax |
string |
1..1 |
The syntax used to describe the variation. The value should be one of the supported syntaxes. |
|
value |
string |
1..1 |
The expression of the variation in the specified syntax. The value should be a valid expression in the specified syntax. |
|
syntax_version |
string |
0..1 |
The version of the syntax used to describe the variation. This is particularly important for HGVS expressions, as the syntax has evolved over time. |
