ORF” (open reading frame) is a  leafconcept of the “ FunctionalityType” concept of identification (generated from the  IDENTIFICATION Axiom) of  IMGT-ONTOLOGY, the global reference in  immunogenetics and  immunoinformatics (Giudicelli and Lefranc 1999; Lefranc et al. 2004, 2005, 2008; Duroux et al. 2008), built by IMGT®, the international ImMunoGeneTics information system® (http://www.imgt.org) ( IMGT® Information System).

ORF” identifies, whatever the molecule type (  MoleculeType), the functionality of  Molecule_EntityType leafconcepts in undefined or germline configuration (  Configuration Type), whose coding region has an open reading frame (ORF), but:
  • Alterations have been described in the splicing sites, recombination signals ( Recombination Signal (RS)) and/or regulatory elements

  • And/or changes of conserved amino acids have been suggested by the authors to lead to uncorrect folding

  • And/or the entity is an orphon ( Location Type)

“ORF” is one of the three leafconcepts...
