• AnatomicalEntityToAnatomicalEntityAssociation
• BehaviorToBehavioralFeatureAssociation - An association between an mixture behavior and a behavioral feature manifested by the individual exhibited or has exhibited the behavior.
• CaseToPhenotypicFeatureAssociation - An association between a case (e.g. individual patient) and a phenotypic feature in which the individual has or has had the phenotype.
• CellLineToDiseaseOrPhenotypicFeatureAssociation - An relationship between a cell line and a disease or a phenotype, where the cell line is derived from an individual with that disease or phenotype.
• ChemicalAffectsGeneAssociation - Describes an effect that a chemical has on a gene or gene product (e.g. an impact of on its abundance, activity, localization, processing, expression, etc.)
• ChemicalEntityAssessesNamedThingAssociation
• ChemicalEntityOrGeneOrGeneProductRegulatesGeneAssociation - A regulatory relationship between two genes
• ChemicalGeneInteractionAssociation - describes a physical interaction between a chemical entity and a gene or gene product. Any biological or chemical effect resulting from such an interaction are out of scope, and covered by the ChemicalAffectsGeneAssociation type (e.g. impact of a chemical on the abundance, activity, structure, etc, of either participant in the interaction)
• ChemicalOrDrugOrTreatmentToDiseaseOrPhenotypicFeatureAssociation - This association defines a relationship between a chemical or treatment (or procedure) and a disease or phenotypic feature where the disesae or phenotypic feature is a secondary undesirable effect.
• ChemicalToChemicalAssociation - A relationship between two chemical entities. This can encompass actual interactions as well as temporal causal edges, e.g. one chemical converted to another.
• ChemicalToDiseaseOrPhenotypicFeatureAssociation - An interaction between a chemical entity and a phenotype or disease, where the presence of the chemical gives rise to or exacerbates the phenotype.
• ChemicalToPathwayAssociation - An interaction between a chemical entity and a biological process or pathway.
• ContributorAssociation - Any association between an entity (such as a publication) and various agents that contribute to its realisation
• DiseaseOrPhenotypicFeatureToGeneticInheritanceAssociation - An association between either a disease or a phenotypic feature and its mode of (genetic) inheritance.

• GeneToDiseaseOrPhenotypicFeatureAssociation
• GeneToExpressionSiteAssociation - An association between a gene and a gene expression site, possibly qualified by stage/timing info.
• GeneToGeneAssociation - abstract parent class for different kinds of gene-gene or gene product to gene product relationships. Includes homology and interaction.
• GeneToGeneFamilyAssociation - Set membership of a gene in a family of genes related by common evolutionary ancestry usually inferred by sequence comparisons. The genes in a given family generally share common sequence motifs which generally map onto shared gene product structure-function relationships.
• GeneToPathwayAssociation - An interaction between a gene or gene product and a biological process or pathway.
• GenotypeToDiseaseAssociation
• GenotypeToGeneAssociation - Any association between a genotype and a gene. The genotype have have multiple variants in that gene or a single one. There is no assumption of cardinality
• GenotypeToGenotypePartAssociation - Any association between one genotype and a genotypic entity that is a sub-component of it
• GenotypeToPhenotypicFeatureAssociation - Any association between one genotype and a phenotypic feature, where having the genotype confers the phenotype, either in isolation or through environment
• GenotypeToVariantAssociation - Any association between a genotype and a sequence variant.
• InformationContentEntityToNamedThingAssociation - association between a named thing and a information content entity where the specific context of the relationship between that named thing and the publication is unknown. For example, model organisms databases often capture the knowledge that a gene is found in a journal article, but not specifically the context in which that gene was documented in the article. In these cases, this association with the accompanying predicate ‘mentions’ could be used. Conversely, for more specific associations (like ‘gene to disease association’, the publication should be captured as an edge property).
