Variation

Note

This class is imported from VRS. Its full documentation can be found in the latest VRS specification at vrs.ga4gh.org.

Trial Use

May change in future releases. See Maturity Model.

Abstract Class — not instantiated directly; concrete subclasses inherit its attributes.

Sealed — Variation has a closed, exhaustive set of concrete subclasses; every one is listed below. No other subclass is permitted, and a conforming instance must be exactly one of these types.

Computational Definition

A representation of the state of one or more biomolecules.

Information Model

Some Variation attributes are inherited from Ga4ghIdentifiableObject.

Field	Flags	Type	Limits	Description
id		string	0..1	The ‘logical’ identifier of the Entity 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.
type		string	1..1	The name of the class that is instantiated by a data object representing the Entity.
name		string	0..1	A primary name for the entity.
description		string	0..1	A free-text description of the Entity.
aliases	⋮	string	0..m	Alternative name(s) for the Entity.
extensions	⋮	Extension	0..m	A list of extensions to the Entity, that allow for capture of information not directly supported by elements defined in the model.
digest		string	0..1	A sha512t24u digest created using the VRS Computed Identifier algorithm.
expressions	⋮	Expression	0..m

This class must match one of the following:

• Adjacency
