Protein Sequence Consequence

Definition and Information Model

Note

This data class is at a trial use maturity level and may change in future releases. Maturity levels are described in the GKS Maturity Model.

Computational Definition

A change that occurs in a protein sequence as a result of genomic changes. Due to the degenerate nature of the genetic code, there are often several genomic changes that can cause a protein sequence consequence. The protein sequence consequence, like a Canonical Allele, is defined by an Allele that is representative of a collection of congruent Protein Alleles that share the same altered codon(s).

Information Model

A ProteinSequenceConsequence is a Categorical Variant with exactly one constraint:

  1. A Defining Allele Constraint with the .relations array containing only a translation_of code. This constraint MUST refer to a protein variant for the allele.

Examples

The following are example implementations of that satisfy the CanonicalAllele recipe:
