GRCh38/hg38 7p22.1(chr7:5905831-6014161)x3
Source: ClinVar variation 151061: GRCh38/hg38 7p22.1(chr7:5905831-6014161)x3
Recipes that this example satisfies: Categorical CNV
Attributes
This example represents the same ClinVar variant as categoricalCnv-ex1, with all top-level attributes populated identically. The distinction between the two examples lies solely in the constraint applied.
id: clinvar:151061, where 151061 is the Variation ID listed within the Identifiers section of ClinVar’s Variant Details.type: CategoricalVariant, as required by the specification.name: GRCh38/hg38 7p22.1(chr7:5905831-6014161)x3, the human-readable label listed within the Identifiers section of ClinVar’s Variant Details.description: A brief placeholder note, as ClinVar does not contain a longform description of this variant.aliases: All listed HGVS representations within ClinVar’s Variant Details for the variant: the GRCh38 (NC_000007.14) and GRCh37 (NC_000007.13) genomic representations.extensions: The cytogenetic location (7p22.1) and ClinVar variation type (copy number gain) are obtained from ClinVar’s Variant Details. The hgvs list extension includes the GRCh38 and GRCh37 HGVS genomic representations.mappings: Mappings to ClinVar’s page for the variant and dbVar are included from the Links section of ClinVar’s Variant Details.
Constraints
Copy Change Constraint: The copyChange field is set to gain, matching the copyChange value within the VRS CopyNumberChange objects listed under members. This contrasts with categoricalCnv-ex1, which uses a Copy Count Constraint to specify an exact copy count of 3.
Defining Location Constraint: The defining location is a VRS Sequence Location on chromosome 7 (refseq:NC_000007.14, GRCh38) spanning positions 5,905,831 to 6,014,161, extracted from the GRCh38 CopyNumberChange included within members. The matchCharacteristic is set to is_within, and a liftover relation is included to link the GRCh38 and GRCh37 representations.
Members
The members field includes two VRS CopyNumberChange objects generated using the VICC Variation Normalizer from the HGVS representations of this variant: NC_000007.14:g.(?_5905831)_(6014161_?)dup (GRCh38) and NC_000007.13:g.(?_5945462)_(6053792_?)dup (GRCh37). Both members have a copyChange value of gain.
