pgo

is a Ontology.

The Pseudogene Ontology (PGO) is an ontology for classifying and annotating pseudogenes based on their evolutionary origins, functional characteristics, and genomic features. Pseudogenes are genomic loci that resemble functional genes but have lost their coding capacity through various mechanisms including frameshift mutations, premature stop codons, or loss of regulatory elements. PGO provides a structured vocabulary for describing different types of pseudogenes (processed, duplicated, unitary) and their relationships to functional genes.
