Copy Number Change

Draft

May change significantly in future releases. See Maturity Model.

Computational Definition

An assessment of the copy number of a Location within a system (e.g. genome, cell, etc.) relative to a baseline ploidy.

GA4GH Digest

Prefix	Inherent
CX	[‘copyChange’, ‘location’, ‘type’]

Information Model

Some CopyNumberChange attributes are inherited from Variation.

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	MUST be “CopyNumberChange”
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
location		iriReference | SequenceLocation	1..1	The location of the subject of the copy change.
copyChange		string	1..1	MUST use one of the defined enumerations that are based on the corresponding EFO ontological terms for copy number variation. See Implementation Guidance for more details.
