TP53 Loss

Source: CIViC variant id 4452: TP53 Loss

Recipes that this example satisfies: None

Attributes

• id: civic.vid:4452, where vid stands for Variant ID, derived from the Variant ID provided by CIViC.

• type: CategoricalVariant, as required by the specification.

• name: TP53 Loss, the name of the variant as provided by CIViC.

• description: A plain text description of the variant noting that TP53 Copy Number Loss is a categorical copy-number variant resulting from the deletion of one copy of the TP53 gene.

• aliases: TP53 Copy Number Loss is provided to clearly specify that this is a copy number event.

• extensions: The cytogenetic location (17p13) was obtained from HGNC for TP53.

• mappings: Mappings to CIViC’s page for TP53 Loss (exactMatch) and the related CIViC molecular profile for TP53 Deletion (relatedMatch) are included.

Constraints

Defining Location Constraint: The defining location is a VRS Sequence Location on chromosome 17 (refseq:NC_000017.11, GRCh38) spanning the genomic region of the TP53 gene (positions 7,668,420 to 7,687,490). The matchCharacteristic is set to is_within, and a liftover relation is included.

Feature Context Constraint: The featureContext is a MappableConcept for TP53 (hgnc:11998), with a primaryCoding linking to its HGNC entry and a cytogenetic location extension of 17p13.1.

Copy Change Constraint: The copyChange field is set to loss to specify the category of copy change.

Members

This example does not include members, as VRS does not support large-scale copy-number events of this type.
