VariO_logo

Variation Ontology, VariO, is an ontology for standardized, systematic description of effects, consequences and mechanisms of variations. VariO allows unambiguous description of variation effects as well as computerized analyses over databases utilizing the ontology for annotation. VariO is a position specific ontology that can be used to describe effects of variations on DNA, RNA and/or protein level, whatever is appropriate.

VariO allows

consistent naming
annotation of variation effects
data integration
comparison of variations and datasets
statistical studies
development of sofware tools


The VariO ontology can be viewed using an ontology editor, such as OBO-Edit or the AmiVariO. AmiVariO is courtesy of AmiGO Gene Ontology browser. VariO is available in OBO, OWL and OWX formats here.
