obsolete canonical allele

ID: GENO_0000890

One of a set of sequence features or haplotypes that exist at a particular genetic locus.

As a 'sequence feature or collection' (sensu SO), a 'canonical allele' is considered here as an extent of biological sequence encoded in nucleic acid molecules of a cell or organism (as opposed to an information artifact that is about such a sequence). Canonical alleles can include haplotypes that contain more than one discontinuous sequence alteration that exist in cis on the same chromosomal strand. In the ClinGen allele model, 'canonical alleles are contrasted with 'contextual alleles'. Contextual alleles are informational representation that describe a canonical allele using a particular reference sequence. A single canonical allele can be described by many contextual alleles that each use a different reference sequence in their representation (e.g. different chromosomal or transcript references)
