ExternalPosition

ExternalPosition defines one end of a ReferenceCoordinate as a location that is external to the corresponding ReferenceSequence. ExternalPosition is used to define coordinates for intronic alleles with respect to a transcript.

Scope and Usage

See TranscriptReferenceCoordinate for details on the Scope and Usage of ExternalPosition.

Exclusions and Limitations

The relationship between the transcript and the genomic sequence to which it is mapped is partially modeled, the details of the mapping are not modeled.

Attributes

Attribute Name Attribute Type Cardinality
offsetLength int 1
offsetDirection Code 1
genomicIndex int 1

offsetLength: intronic offset of the Position. Used in coordination with the index attribute of the Position. This is the distance into the intron from the location of the index in the TranscriptReferenceSequence.

offsetDirection: Declares whether the intron is to the 5-prime or 3-prime direction of the Position index.

genomicIndex: the index of this position in the given GenomicReferenceSequence.

Relationship Name Entity Type Cardinality
genomicReferenceSequence GenomicReferenceSequence 1

genomicReferenceSequence: A GenomicReferenceSequence to which this transcript has been mapped.
